Version added:1.0.serialize ()
A collection object that runs in a jquery representing a form of element. The table element can be of the following types
<form>
<div><input type= "text" Name= "a" value= "1" id= "a"/></DIV>
< Div><input type= "text" name= "B" value= "2" id= "B"/></DIV>
<div><input type= "hidden" Name= "C" value= "3" id= "C"/></DIV>
<div>
<textarea name= "D" rows= "8 "Cols=" >4</textarea>
</div>
<div><select name= "E"
<option value= "5" selected= "selected" >5</OPTION>
<option value= "6 ">6</option>
<option value=" 7 ">7</OPTION>
</select> </div>
<DIV>
<input type= "checkbox" Name= "F" value= "8" id= "F"/>
</DIV>
<div>
<input type= "Submit" name= "G" value= "submit" Id= "G"/>
</div>
</form>
The serialize () method can process a jquery object, select individual form elements, such as <input>, <textarea>, and < selections. However, it is usually easier to choose <form> mark as serialization itself:
$ (' form '). Submit (function () {
Alert ($ (this). Serialize ());
return false;
});
This produces a standard-looking query string:
A=1&b=2&c=3&d=4&e=5
Only "successful control" is serialized to a string. The value of no submit button is serialized as the use button is not submitted. There must be a name attribute for the element contained in the serialized string for the value of the form element. The data in the selection element from the file is not serialized.
For example:
The serialized form of the query string, which may be an AJAX request sent to the server.
