This article is about how to use serialize() in jQuery. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

jQuery successfully serializes control forms. Only form elements check the input boxes they contain; in all other cases, input elements to serialize should be part of a collection passed to the.serialize() method. Selecting strings in which a form and its child elements are serialized in a collection results in duplication.

Note: Only "successful controls" can be serialized into strings. The value of the submit button is not serialized. In addition, if you want the value of a form element to be serialized into a string, the element must contain a name attribute. In addition, checkbox and radio button (input type "radio" or "checkbox") values are serialized only when selected. In addition, the data for file selection elements is not serialized.

Examples:

Serialize a form into a query string that can be sent in an Ajax request.

body, select { font-size:12px; }

form { margin:5px; }

p { color:red; margin:5px; font-size:14px; }

b { color:blue; }

function showValues() {

var str = $("form").serialize();

$("#results").text(str);

}

$(":checkbox, :radio").click(showValues);

$("select").change(showValues);

showValues();
