How to set input elements to be non-editable in jquery

jQuery is a popular JavaScript library that provides developers with many useful functions and methods to make web development easier and more efficient. In web development, we often encounter situations where we need to set certain input elements to be non-editable. This article will introduce how to set input elements to be non-editable using jQuery.

Why should we set the input element to be non-editable?

Sometimes, we need to display certain data in the form, but do not want users to modify the data. In this case, we need to set the input element to be non-editable. In addition, in the form, some input elements are read-only, that is, the user can view but not edit. These scenarios require the input element to be set to non-editable to ensure the correctness and completeness of the form data.

The prop() method of jQuery sets the input element to be non-editable

The prop() method of jQuery can be used to get and set the attribute value of the HTML element. To make an input element non-editable, simply set its "readonly" attribute to true. The code is as follows:

$(document).ready(function(){
    $("input").prop("readonly", true);
});

The above code will set all input elements to read-only, that is, not editable. If you only want to make certain input elements non-editable, you can use a class selector or ID selector to filter the elements and set them. For example, to set all input elements with the class name "my-input" as read-only, the code is as follows:

$(document).ready(function(){
    $("input.my-input").prop("readonly", true);
});

If you want to set the input element with a specific ID as read-only, the code is as follows:

$(document).ready(function(){
    $("#my-input").prop("readonly", true);
});

jQuery's attr() method sets the input element to be non-editable

In addition to using the prop() method, you can also use the attr() method to set the input element to be non-editable. The code is as follows:

$(document).ready(function(){
    $("input").attr("readonly", true);
});

Compared with the prop() method, the attr() method can set more attributes, but when setting boolean type attributes, the prop() method is more useful.

Summary

Through this article, we learned how to set the input element to be non-editable using jQuery. An input element can be made read-only by setting the "readonly" attribute to true. When using the prop() method and the attr() method, please note that the prop() method is suitable for setting properties of the boolean type, while the attr() method is suitable for all types of properties. Just choose the appropriate method based on specific scenarios and needs.
