jquery input settings are not editable
jQuery is a popular JavaScript framework that helps developers quickly write code to implement various functions. One of the common requirements is to set the input to a non-editable state. In this article, we will introduce how to use jQuery to achieve this functionality.
1. Set the input to be non-editable through element attributes
One of the simplest methods is to use the "disabled" attribute of the input element to set it to a non-editable state. In HTML, you can add the "disabled" attribute to the input tag to achieve this function. For example:
In jQuery, you can use the attr() function to manipulate the attributes of the input element. To disable an input element, simply set its "disabled" attribute to true. For example:
$('input[name="username"]').attr('disabled', true);
These codes will select those with "name" attribute as "username" input element and set its "disabled" attribute to true to disable the input box.
To enable the input box, just set the "disabled" attribute to false. For example:
$('input[name="username"]').attr('disabled', false);
2. Use the prop() function to set the input to be non-editable
Another common method is to use the "readonly" attribute of the input element. Unlike the "disabled" attribute, the "readonly" attribute retains the text content in the input box but does not allow the user to edit it. In HTML, you can add the "readonly" attribute to the input tag to achieve this function. For example:
In jQuery, you can use the prop() function to manipulate the properties of an element. If you want to set the input element to read-only mode, you can use the following code:
$('input[name="username"]').prop('readonly', true);
These codes will select the input element with the "name" attribute as "username" and set its "readonly" attribute to true, thereby setting it to read-only mode.
To disable read-only mode, simply set the "readonly" attribute to false. For example:
$('input[name="username"]').prop('readonly', false);
3. Use CSS styles to set the input to be non-editable
The last method is to use CSS styles to set the input box to an uneditable state. The following styles can be added to the input element through CSS settings:
input[readonly] {
background-color: #eee;
cursor: not-allowed;
}
These styles will make the background of the input box gray and the cursor turn into a prohibition sign, letting users know that the input box is not editable.
To enable the input box, simply remove the "readonly" attribute from the input box. For example:
In either method, we can easily set the input to a non-editable state using jQuery. You can choose which method to use based on your specific needs. In any case, these functions and properties are easy to understand and use, and even if you are a beginner, you can easily find the appropriate method to meet your needs.
