I am using jQuery for a cascading check box, but the getJSON
command dosen't work on the server (locally it works fine). It couldn't find the data.json
file (see error debug).
Part of the script:
<script type="text/javascript" src="scripts/jquery-1.7.2.js"></script>
<script>
$(function() {
$("#json-one").change(function() {
var $dropdown = $(this);
$.getJSON("data.json?callback=?", function(data) {
var key = $dropdown.val();
var vals = [];
switch(key) {
case 'BR9':
vals = data.BR9.split(",");
break;
case 'base':
vals = ['Please choose from above'];
}
var $jsontwo = $("#json-two");
$jsontwo.empty();
$.each(vals, function(index, value) {
$jsontwo.append("<option>" + value + "</option>");
});
});
});
});
</script>
Error from firebug:
GET http://______my url site ____/data.json 404 NOT FOUND x 25ms
If I change the line
$.getJSON("data.json", function(data) ...
to
$.getJSON("data.json?callback=?", function(data) ...
it doesn't work either.
Can anyone help me?
您是否尝试提供json文件的完整路径?
$.getJSON("http://www.mywebsite.com/folder/data.json?callback=?", function(data) {});
Is the page you are making JSON call from and the page you are making the call to are on the same domain ? JSON doesn't support cross domain calls and you would need to use JSONP.
