Events triggered by jquery's carriage return binding

This article describes how jquery captures the events triggered by the carriage return key. For more information, see section 1. jquery captures the carriage return key:

The Code is as follows:

$ ("Html"). die (). live ("keydown", function (event ){
If (event. keyCode = 13 ){
// Add the logic to be processed here
}
});

// Bind the carriage return action
$ ('Textarea [name = chattext] '). keydown (function (event ){
If (event. which = 13 ){

}
});

2. jquery obtains multiple checkbox values:

The Code is as follows:

$ ('Input [type = "checkbox"] [name = "types"]: checked'). each (function (){
Types = types + $ (this). val () + "| ";
}
);

3. jquery asynchronous request method:

The Code is as follows:

$. Ajax ({
Url: "$ {pageContext. request. contextPath}/UOSRoleManangerAction. do? Method = createRole ",
Type: "post ",
DataType: "html ",
Data: {"roleName": roleName, "roleDescription": roleDescription, "roles": roles, "types": types },
Success: function (data ){
Var dataObj = eval ("(" + data + ")");
If (dataObj. result ){
Alert ("operation successful! ");
SubmitForm (null, "initPage ");
} Else {
Alert ("operation failed! ");
}
}
});
