jQuery验证多个动态添加的字段
[英]jquery validate multiple dynamically added fields
问题描述
I am trying to validate multiple dynamically added fields on a form before submit using jquery but when one field is valid, the form is being submitted: http://jsfiddle.net/cvL0ymu7/ . 
我正在尝试在使用jquery提交之前验证表单上的多个动态添加的字段，但是当一个字段有效时，正在提交表单： http : //jsfiddle.net/cvL0ymu7/ 。 How can I validate all fields before the submit. 如何在提交之前验证所有字段。
<html>
<body>
<form action="#" method="post">
<div id="fields"></div>
<input type="submit" value="Submit" />
</form>
<button id="test">Add field</button>
</body>
</html>
Le JavaScript JavaScript
$(function() {
$("#test").click(function(){
var unique_id = new Date().getTime();
$("#fields").append("<input class='myfield' type='text' name='myfield_" + unique_id + "'/><br />");
});
$( "form" ).submit(function( event ) {
if ( $( ".myfield" ).val() !== "" ) {
alert("form is valid");
//$( "span" ).text( "Validated..." ).show();
return;
}
//$( "span" ).text( "Not valid!" ).show().fadeOut( 1000 );
alert("form is invalid");
event.preventDefault();
});
});
