Form is a required field. Checking required fields

The checkRequired() function checks each element in the form for the required attribute. If the attribute is found, then it is checked whether the input was made.

JavaScript

Since the check is performed on the client side, and the script runs directly in the user’s browser, warnings look different in Google Chrome, Mozilla Firefox, Opera and Yandex Browser.

It would seem that there is nothing complicated in the design of input fields: draw empty rectangles for entering data, the user will do the rest himself. However, everything is not so simple. Judging by the length of the article, it is clear that there are quite a lot of rules and features. The user needs to be carefully “guided by the hand”, shown everything, explained and helped. Then and only then will we be able to get the desired data from him. Well, let's start!

7+ input field rules

The most basic rule, as everywhere else, is to put yourself in the place of the visitor. Is everything clear? Is it possible to understand at first glance what needs to be entered in the field? Does the field respond adequately to the information entered?

Write descriptions and tips

Hints and descriptions are needed to show what data needs to be entered, how to enter it correctly, and how the site will use this information in the future.

There are several types of hints:

1) Icons

Icons are a universal visual language. They help you understand what to enter even with a quick glance. And yes, icons are a design fetish =)

However, we should not forget that they always need to be explained.

2) Examples

The easiest way to tell how to fill out a field is to show an example. Sample example: " [email protected]»

3) Explanations

This type of description serves to explain how the site will use the data and what it is needed for. For example: “We need mail to notify you about the status of your order. We will not send spam."

Use masks

For fields that require data formatted in a certain way (for example, a bank card number or phone number), masks should be used. Thus, we shift the work of formatting information from the visitor’s shoulders to a soulless machine.

Here are some examples of different masks:

Highlight required fields

If among the optional fields there are fields that are required to be filled in, then they should be highlighted among others and emphasis should be placed on their mandatory completion. As a rule, required fields are indicated with an asterisk - *.

It is better to group all required fields together and place them at the beginning of the form.

By the way, the example above also shows 2 types of tips: examples and explanations.

Focus and keyboard

The active field in which the cursor is positioned must have a distinctive feature. As a rule, browsers independently highlight active fields. However, you should not leave everything to chance and check the functionality of this function yourself.

When the page loads, the first input field should automatically become active. As if inviting you to fill out the entire form. When filling out a form, it should be possible to switch between input fields without using the mouse. This usually happens by pressing the Tab button.

When using hints with auto-completion (for example, in a search), it should be possible to select an item using arrows and confirm it by pressing the Enter key.

When entering secret data (for example, a password), it should be possible to hide and show this data at the user's request.

Use the data already entered

Input fields need to remember things that ordinary people forget. It is rude to ask for the same information twice. If you once subscribed to the site’s mailing list, then when registering, the site should remember you and enter your email in the appropriate field.

Group input fields

For ease of filling out, it is better to group similar fields together. For example, fields for entering personal information (first name, last name, email) are one block, fields with a delivery address are another block.

Be aware of the field size

The field size in most cases serves to estimate the amount of data that is required from the user. Those. where you need to enter a long address, the field is large. So where a 6-digit index is needed, the field is small.

Finally

The design of input fields is not as simple as it seems at first glance. You need to remember many nuances and constantly ask yourself the question: “will everything be clear to the user?”

Many meticulous guys will say that there weren’t 7 rules at all (and some didn’t even notice, ha ha ha). However, many of the rules are small, so I counted them as half. And in general, I just like the number 7 =)

On almost every website you can see a registration form. Of course, there are those who simply took someone else’s form, inserted it into their own, and then the user wants to register, but cannot. There are cases that during registration a certain password is allowed and you are able to register, but then when you try to log into the site, an error appears that this is an invalid password, and so the site loses a certain number of visitors, so be careful.

A real example can be seen here:

This is not the first lesson on this topic, perhaps you have not seen the previous ones and they will be interesting to you:

HTML part

Let's see what this form consists of:

If you have studied past lessons, then you will be familiar with attributes such as placeholder And required.

But I’ll repeat it again:

placeholder— the presence of this attribute means that in the background of this text field there will be the text specified in the value of this attribute. And when you type it disappears.

required— if a field has this attribute, then the field is required.

And we didn't use Javascript because HTML5 allows us to do this with its functions.

There is also a new attribute here pattern="(http|https)://.+"— it specifies what the site’s web address should begin with, otherwise there will be an error.

CSS part

Now we are done with the HTML part and we need to give our form a look. Because all form elements are in an unordered list, therefore using the appropriate selectors will set styles:

The last property means that we set a border to the first and last element of the list. Next, we will define the main styles for form elements:

Now let’s write styles for when the fields are active and when they are not:

Left just a little bit:). The penultimate step is to set styles for tooltips:

;

position: absolute;

top: 1px;

• Interfaces

• Translation

Web forms play a big role in the daily use of the Internet. If you develop websites, then most likely they are present in them: be it a simple feedback form or a sophisticated web application. Here are some tips to help you create easy-to-use forms.

1. Clearly mark required fields

On the Zappos.com registration form, required fields are marked with an asterisk (*). Optional fields are also clearly marked.

2. Use clear and detailed error messages

3. Use client-side data format validation (JavaScript)

The SurveyGizmo registration form lets you know if the email address you entered is not formatted correctly.

4. Visually highlight fields to fill out so that the user doesn’t get lost

A Wufoo web form visually highlights active elements with a background color.

Google Chrome highlights the active element with a yellow frame. Firefox light blue.

5. Show progress results

The Amazon checkout has 4 pages. The form tells you where you are now and how much time is left until completion.

6. Periodically save (cache) form data

7. Do not use the standard “Submit” text (send)

On the Basecamp registration form, the “Submit” text has been replaced with something more useful.

8. The “Cancel” button makes you hesitate

9. Show users fields in the correct format

Geico's registration form provides clear instructions on what format the input data is expected to be in.

10. Single-column form is the best solution

Single column form

Backpack's registration form is a single-column form.

Form with multiple columns

4. Exercises are performed according to IPF rules

Squats(rules and order of execution).

After removing the bar (assistants can provide assistance), the athlete takes the starting position.

After the athlete has accepted the starting position, the judge gives the command to SIT DOWN.

The athlete squats so that the top of the legs at the hip joints is lower than the top of the knees. Only one attempt to make a downward movement is allowed.

The athlete must independently return to a vertical position with legs fully straightened at the knees. Double standing up (“jumping” is prohibited).

As soon as the athlete takes a stationary position, the referee gives the command to return the barbell to the racks - RACKS.

- Prohibited- Failure to comply with the senior referee’s signals when starting or finishing an exercise. Double stand-up (jump) from the bottom of a squat position or any downward movement while standing up. The mistake is to bend the legs at the knees and lower the body to a position where the upper surface of the legs at the hip joints is lower than the top of the knees.

Bench press(rules and order of execution)

The athlete should lie on his back, with his head, shoulders and “whole” buttocks in contact with the surface of the bench. The sole and heels of his shoes must be in contact with the surface of the platform or blocks (as far as the shape of the shoes allows).

The fingers should wrap around the bar lying on the racks, with the thumbs positioned “locked” around the bar. This position must be maintained during

performing the exercise. The use of a reverse grip is prohibited.

To ensure firm support for the legs, the athlete can use flat slabs or blocks no higher than 30 cm from the surface of the platform.

The distance between the hands on the bar, which is measured between the index fingers, should not exceed 81 cm (both index fingers should be inside the 81 cm marks).

After removing the bar from the racks with or without the help of assistants, the athlete must wait for the signal from the senior judge with his arms fully straightened (“on”) at the elbows.

The signal to begin the press must be given as soon as the lifter assumes a stationary position.

position and the bar will be in the correct position. The signal to start the exercise is the command – START.

After receiving the signal, the athlete must lower the barbell to his chest and hold it in a stationary position on his chest (usually the base of the sternum), after which the judge gives the command - PRESS. Then the athlete must press the barbell up into straight arms. After fixing the bar in this position, the judge gives the command - RACKS.

- Prohibited– Any error in following the referee’s commands. Any change in the starting position when performing an exercise (any lifting (separation) of the head, shoulders, buttocks from the bench or movement of the legs on the platform or blocks, or movement of the arms along the bar). Any downward movement of the barbell during a bench press. Lack of squeezing the barbell with fully straightened arms at the end of the exercise.

6. Deadlift (rules and order of execution)

The athlete must face the front of the platform. The barbell, which is located horizontally in front of the athlete’s legs, is held with a free grip with both hands and rises up until the athlete stands upright.

Upon completion of lifting the barbell in the deadlift, the knees should be fully straightened and the shoulders should be pulled back.

The judge gives the command - DOWN.

Any lifting of the barbell or any deliberate attempt to lift it is considered an approach. Once the lift has begun, no downward movement of the barbell is allowed until the lifter reaches a vertical position with the knees fully extended. If the bar sag when the shoulders are pulled back, this is not a reason not to count the weight lifted.

- Prohibited– any downward movement until the final position is reached. Supporting the barbell with your thighs while lifting up. Steps back or forward. Lowering the barbell to the command. Releasing the barbell from your hands when executing the downward command.
