Jquery captures the Enter key and obtains the checkbox value and the asynchronous request method,

This document describes how jquery captures the Enter key and obtains the checkbox value and asynchronous request. We will share this with you for your reference. The details are as follows:

1. jquery:

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

2. jquery obtains multiple checkbox values:

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

3. jquery asynchronous request method:

$. Ajax ({url: "$ {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! ");}}});
