Hi all,
I am learning how to use
JQuery to help check data availability.
To start with it, I wrote a few lines of codes using cakePHP.
I have written a function in a Controller for checking data input, and the URL is like this:
http://www.mywebsite.com/controllers/action/avariable
I was trying to pass the value in a Input TextBox field using the
JQuery Ajax to the URL above,but I don't know why it is not working in passing a variable to the Controller's action. Could you help me out please?
<Script language="javascript">
//<!--
$(document).ready(function(){
$(document).change(function() {
var usr = $("#data\\[User\\]\\[name\\]").val();
if(usr.length >= 3){
$("#username").append('<span><img align="absmiddle" src="loader.gif" />Checking</span>');
$.ajax({
type: "POST",
url: "http://www.mywebsite.com/controllers/action/",
data: usr,
success: function(msg){
if(msg == 'OK')
{
$("#username").append('<span><img align="absmiddle" src="accepted.png"/></span>');
}
else
{
$("#username").append('<span>'+msg+'</span>');
}
}
});
}
else
{
$("#username").append('<span>The username should have at least 3 characters.</span>');
}
});
});
//-->
</Script>
<form name="adduser" id="adduser" method="post" action="/controllers/action2">
<table border=0 width="100%">
<tr>
<td>Username</td>
<td>
<div id="username">
<input type=text name="data[User][name]" id="data[User][name]">
</div>
</td>
</tr>
<tr>
<td>
<input type="submit" value="Send">
</td>
</tr>
</table>
</form>
