First: Change the Boolean state of the disabled, the specific code and interpretation as follows:
The code is as follows:
Copy Code code as follows:
$ ("Button:eq (2)"). Click (function () {
var text2=$ ("Input:text:eq (2)");
if (text2.attr ("disabled") ==false) {
Set the third text input box disabled property to True by setting the Boolean property of disabled
Text2.attr ("Disabled", true);
}else{
Remove the disabled property by placing the third text input box disabled property to False
Text2.attr ("Disabled", false);
}
});
The second: Remove the disabled attribute, the specific code and explain as follows:
The code is as follows:
Copy Code code as follows:
$ ("Button:eq (1)"). Click (function () {
var text2=$ ("Input:text:eq (1)");
if (text2.attr ("disabled") ==false) {
Sets the second text input box to disabled by setting the value of the disabled
Text2.attr ("Disabled", "disabled");
}else{
Remove the Disable property of the second text input box by removing it
Text2.removeattr ("Disabled");
}
});
The third: Change the value of the disabled, the specific code and explanation as follows:
The code is as follows:
Copy Code code as follows:
$ ("Button:eq (0)"). Click (function () {
var text1=$ ("Input:text:eq (0)");
if (text1.attr ("disabled") = = "") {
or text1.attr ("disabled") ==false
Sets the first text input box to disabled by setting the value of the disabled
Text1.attr ("Disabled", "disabled");
}else{
Clears the disabled property in the first text input box by overriding
Text1.attr ("Disabled", "");
}
});
The complete sample code is as follows (tested through):
The code is as follows:
Copy Code code as follows:

Sets the first text input box to disabled by setting the value of the disabled
Text1.attr ("Disabled", "disabled");
} else {
Clears the disabled property in the first text input box by overriding
Text1.attr ("Disabled", "");
}
});
$ ("Button:eq (1)"). Click (function () {
var Text2 = $ ("Input:text:eq (1)");
if (text2.attr ("disabled") = = False) {
Sets the second text input box to disabled by setting the value of the disabled
Text2.attr ("Disabled", "disabled");
} else {
Remove the Disable property of the second text input box by removing it
Text2.removeattr ("Disabled");
}
});
$ ("Button:eq (2)"). Click (function () {
var Text2 = $ ("Input:text:eq (2)");
if (text2.attr ("disabled") = = False) {
Set the third text input box disabled property to True by setting the Boolean property of disabled
Text2.attr ("Disabled", true);
} else {
Remove the disabled property by placing the third text input box disabled property to False
Text2.attr ("Disabled", false);
}
});
});
