JQuery Page Refreshes
Question
I working on a page with some JQuery and Kendo UI. This is my first JQuery project and I getting things along. However, my page refreshes for some reason. This is what I am trying to do: I have a text field where I can enter a search term and when I press a button, the query is sent to a php file and some json info will pop up. So far, I can get it to return something, but the page refreshs and all the data is gone.
code:
*<!DOCTYPE html>
<html>
<head>
<title>Search</title>
<link href="styles/kendo.common.min.css" rel="stylesheet" />
<link href="styles/kendo.default.min.css" rel="stylesheet" />
<script src="js/jquery.min.js"></script>
<script src="js/kendo.web.min.js"></script>
</head>
<body>
<div id="example">
<form id="search">
<label for="search">Search For:</label>
<input type="text" id="txtSearch" name="q">
<button type="submit" id="submit">Find</button>
</form>
<div id="grid">
</div>
</div>
<script>
$(function() {
$("#grid").kendoGrid({
dataSource: {
transport: {
read: "include/showsearch.php"
},
schema: {
data: "data"
}
},
columns: [{field: "id"},{field: "name"},{field: "season"}]
});
$("#submit").click(function(){
var textVal = $("#txtSearch").val();
var dynamicURL = "include/showsearch.php?show_name=" + textVal;
var grid = $("#grid").data("kendoGrid");
alert("sdf123");
grid.dataSource.transport.options.read.url = dynamicURL;
grid.dataSource.read();
alert("sdf");
});
});
</script>
</body>
</html>*
NOTE: I used the alert functions to stop and see how the page reacts. How do I get the page from refreshing?

The reason this is happening is that the default action for your submit button is still occurring; submitting the form.
It's probably best to catch the form submission event rather than the button click as hitting Enter in a text field may also submit the form.
You will also need to prevent the default event action.
Change this
$("#submit").click(function(){
to this
$('#search').on('submit', function(e) {
e.preventDefault();
// and the rest of your code here
