Summary of JQuery disable/recover buttons readonly and disabled

Next, let's take a look at the readonly and disabled buttons of JQuery. I hope this article will be helpful to you.

Disable/restore button

I used it before, don't remember...

Actually, it is to change the attribute of <input>.

Disable the btn button:

The Code is as follows:	Copy code
$ ("# Btn"). attr ({"disabled": "disabled "}); // Or $ ("# Btn"). attr ("disabled", "disabled ");

Disable:

The Code is as follows:	Copy code
$ ("# Btn"). removeAttr ("disabled "); // Or $ ("# Btn"). attr ("disabled ","");

JQuery's method for applying the disabled and readonly attributes to elements:

1. readonly

$ ('Input'). attr ("readonly", "readonly") // set the input element to readonly
$ ('Input'). removeAttr ("readonly"); // remove the readonly attribute of the input element

If ($ ('input'). attr ("readonly") = true) // you can determine whether the readonly attribute has been set for the input element.

There are two ways to set the readonly attribute for the element and cancel the readonly attribute:
$ ('Input'). attr ("readonly", true) // set the input element to readonly
$ ('Input'). attr ("readonly", false) // remove the readonly attribute of the input element

$ ('Input'). attr ("readonly", "readonly") // set the input element to readonly
$ ('Input'). attr ("readonly", "") // remove the readonly attribute of the input element

2. disabled
$ ('Input'). attr ("disabled", "disabled") // set the input element to disabled
$ ('Input'). removeAttr ("disabled"); // remove the disabled attribute of the input element

If ($ ('input'). attr ("disabled") = true) // you can determine whether the disabled attribute has been set for the input element.

There are two ways to set the disabled attribute and cancel the disabled attribute for the element:
$ ('Input'). attr ("disabled", true) // set the input element to disabled
$ ('Input'). attr ("disabled", false) // remove the disabled attribute of the input element

$ ('Input'). attr ("disabled", "disabled") // set the input element to disabled
$ ('Input'). attr ("disabled", "") // remove the disabled attribute of the input element
