Here we can use three workarounds to change the state of an element that is set to disabled to enabled.
First, change the boolean status of disabled. The code and explanation are as follows:
Copy codeThe Code is as follows: $ ("button: eq (2)"). click (function (){
Var text2 = $ ("input: text: eq (2 )");
If (text2.attr ("disabled") = false ){
// Set the
Jquery APIs provide the following methods to apply 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) // determine whether the readonly attribute has been set for the input element. There are two methods to set the readonly at
ReadOnly and disabled are the two attributes that are used in the form, and they all enable users to not change the content in the form fields. But there is a slight difference between them, summed up as follows:ReadOnly is valid only for input (Text/password) and textarea, and disabled is valid for all form elements, including Select, Radio, CheckBox, Button, and so on.However, when the form element is use

Change the Boolean state of disabled, the following for you to introduce three kinds of relatively good methods, you can refer to the following First: Change the Boolean state of the disabled, the specific code and interpretation as follows:nbsp; nbsp; code as follows:nbsp; nbsp; code as follows: $ ("Button:eq (2)"). Click (function () {nbsp; var text2=$ ("Input:text:eq (2)");nbsp; if (text2.attr ("
ReadOnly and disabled are two properties that are used in a form to make it impossible for users to change the contents of a form field. But there is a slight difference between them, summed up as follows:
ReadOnly is only valid for input (Text/password) and textarea, and disabled is valid for all form elements, including Select, Radio, CheckBox, Button, and so on.
However, after the form element is used
change wuminpc to mywifi. For example, if you like to name "key", the red letter behind it is the password, and you can name it by yourself. For example, you can change wuminwifi to 12345678, in short, you can name it yourself, not necessarily the network name, this password, the password is better than 8) This command has three parameters, mode: whether to enable virtual WiFi Nic, if it is set to disallow, It is

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
Disable the btn button:
The Code is as follows:
Copy code
$ ("# Btn"). attr ({"disabled": "disabled "});// Or$ ("# Btn").
Disable/Redo button
Used before, not remember ...
is actually changing the properties of
To disable a button with ID btn:
The code is as follows
Copy Code
$ ("#btn"). attr ({"Disabled": "Disabled"});Or$ ("#btn"). attr ("Disabled", "disabled");
Cancel
Jquery sets readonly and disabled of elements.
The Jquery api provides a method to apply the disabled and readonly attributes to elements, which is recorded here. As follows:
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) // de
The Jquery api provides a method to apply the disabled and readonly attributes to the element, if you are interested, you can practice using Jquery APIs to provide methods for applying the disabled and readonly attributes to elements. Here, we will record them. As follows:

The Code is as follows:
$ ('Input'). attr ("readonly", "readonly") // set the input element to readonly.$ ('Input').
The jquery API provides a way to apply disabled and ReadOnly attributes to elements, which are documented here. As follows:1.readonly$ (' input '). attr ("ReadOnly", "ReadOnly")//The INPUT element is set to ReadOnly$ (' input ').

In jquery, you can use jqueryObj. attr ( quot; disabled quot;, quot; disabled quot;) sets an element on the page to editable or trigger, however, the APIreference of jquery does not indicate how to set the page to disable to trigger or editable. Here we can use three workarounds to change the state of an element that is set to disabled to enabled.
First, chang
