jQuery验证显示加载GIF,而远程请求 [英] jquery validation displaying loading GIF while remote requesting
问题描述
我验证与jQuery验证插件的形式。我检查,如果给定的用户名已在数据库与远程选项。一切工作像预期,但我想说明一个加载GIF,同时验证脚本请求的服务器。有没有一种简单的方法来做到这一点还是需要编辑插件的js文件?反正,这里是重presentative code ..
I'm validating a form with the jquery validation plugin. I'm checking if a given username is already in db with the remote option. everything works like expected but I want to show a loading gif while the validation script is requesting the server. Is there an easy way to accomplish this or do I need to edit the plugin js file? anyways, here is the representative code..
rules: {
user_name: {
alfanum:true,//custom method to check if alphanumeric
required: true,
minlength: 5,
remote: {url: "checkuser_custom.php",type:"GET",data:{cmd:"check"}}
}}
所以基本上我想要的readyState 2时,显示一个ajax加载GIF
So basically I want to display an ajax loading gif during readystate 2
