How do I pass a variable in a php file that is loaded into a page (DOM) to a jQuery function??
Iv'e tried various method's while searching online but I haven't figured out how to use them correctly.
I need the var navHeaderTitle to be passes to the jQuery load() callback function so it sets the HTML tag, #navHeaderTitle, to the variable called in the php file.
Thnx for you help.
php:
<?php
$con = mysql_connect("localhost","user","pw");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("db", $con);
$result = mysql_query("SELECT * FROM some_list");
$navHeaderTitle = "MY NEW TITLE";//<--I NEED 2 INJECT THIS!!
while($row = mysql_fetch_array($result))
{
echo "<div id='navItem' title='$navHeaderTitle'>";
echo "<h1>" . $row['label'] . "</h1>";
echo "<h2>" . $row['title'] . "</h2>";
echo "<p>" . $row['description'] . "</p>";
echo "</div>";
}
mysql_close($con);
?>
JavaScript in the HTML Head:
<script type="text/javascript">
var navHeaderTitle = '';
$(document).ready(
function() {
$("#navContent").load('http://url/my_list.php', function() {
$('#navHeaderTitle').text($(html).find('div#navItem').attr('title'));//<--GET THE VAR FROM LOADED PHP FILE!!
});
});
</script>
<body>
<div id="navPanel">
<div id="navHeader">
<img src="images/ic_return.png" style="float: left;"/>
<img id="listSortBtn" src="images/ic_list_sort.png" style="float: right;"/>
<h4 id="navHeaderTitle"></h4>//THIS IS WHAT NEEDS THE VAR DATA!!
</div>
<div id="navScrollContainer" class="navContentPosition">
<div id="navContent">HTML CONTENT from PHP GETS DUMPED IN HERE</div>
</div>
</div>
</body>
Ive tried using this but not sure how to:
$.get('scripts/my_list.php', {}, function(data){
data = split(':');
})
replace echo("$navHeaderTitle"); with
echo("<script> var navHeaderTitle = $navHeaderTitle </script>");
and remove var navHeaderTitle = ''; from the <head> script..
that will setup a JS variable like you're using, but you have to do that before the code in the <head> loads...
EDIT
ok don't echo("$navHeaderTitle"); you can put it into the HTML like:
echo "<div id='navItem' title='$navHeaderTitle'>";
then in the JS you can do:
<script type="text/javascript">
var navHeaderTitle = '';
$(document).ready(
function() {
$("#navContent").load('http://url/my_list.php', function(response) {
$('#navHeaderTitle').text($(response).attr('title'));
});
});
</script>
here's a jsfiddle demo: http://jsfiddle.net/JKirchartz/hdBzF/ (it's using fiddle's /echo/html/ so the load has some extra stuff to emulate the ajax)
I would have the php file return a json object that contains two parts, the html you want to echo and the title you want to use.
Then I would use jQuery's .ajax() function instead of .load() to get the return value from your php script in a javascript variable instead of dumping it directly as .load() does.
It would be cleaner to pass the var in a custom attribute (data-var), then fetch it width JQuery
$(some_element).attr("data-var");
I hate to mess my JS code with php.
