jquery Unbutton Disable

In web development, we sometimes disable a button in some situations, such as to prevent users from repeatedly submitting forms. But sometimes we need to undisable the button after other events are triggered. At this time, you need to use jQuery to achieve it.

jQuery can easily obtain DOM elements and modify the attributes of DOM elements. Therefore, we can use jQuery to quickly find the button that needs to be disabled and change its properties back to their original values.

The specific implementation method is as follows:

1. Add a disabled attribute to the button that needs to be disabled. For example:

Submit button

2. is given to the event that triggers the unlocking (such as after the Ajax request returns successfully) Bind a method. In the method you can use jQuery to find the button element and modify its disabled attribute to false. For example:

//Unlock the button after the Ajax request returns successfully
$.ajax({

url: "xxx", success: function(data) { //找到按钮元素并解禁 $("#submitBtn").attr("disabled", false); }

});

3. Use the above Method makes it easy to disable and undisable individual buttons. But if we need to operate multiple buttons in batches, we can use jQuery's selector to find all the buttons that meet the conditions at once and operate them, for example:

//Disable all those with class disabled-btn Button
$(".disabled-btn").attr("disabled", true);

//Unlock the disabled state of all buttons with class disabled-btn
$(". disabled-btn").attr("disabled", false);

It should be noted that when using jQuery to disable a button, do not set all button attributes to disabled. Otherwise, unexpected problems may occur when users operate other elements. The disable button should only be used when necessary, and be sure to undisable it when appropriate.

To sum up, it is very simple to use jQuery to undisable the button. You only need to find the button that needs to be undisabled and set the disabled attribute to false. However, care needs to be taken to avoid abusing the disabled button to avoid causing trouble to users.
