XML parsing using jQuery instead of Ajax
I was trying to use Ajax to parse XML but it was not working out, so I used the jQuery library which seems a lot simpler to use. I am trying to make a client for a rest service. The service spits out XML and the client should parse it and display it in a table. I don't know what I'am doing wrong the function does not seem to work at out. I would appreciate it if I could get a little bit of guidance.
This is how I call jQuery:
script src="http://code.jquery.com/jquery-1.5.1.js" type="text/javascript"
This is the code:
var HTMLSurveyNames;
function getSurveyNames(){
alert("hery");
$(document).ready(function(){
$.ajax({
type: "GET",
url: "http://survey-creator.appspot.com/rest/surveymakerpro/allsurveys",
dataType: "xml",
success: function(xml) {
HTMLSurveyNames = "<table border='1'><tr>Survey Names<th></th></tr>";
$(xml).find('SurveyList').each(function(){
var surveyName = $(this).find('surveys').text();
HTMLSurveyNames += "<tr><td>"+surveyName+"</td></tr>";

document.getElementById('displayNames').innerHTML = HTMLSurveyNames;
});
}
});
});
}
This is where I would want the table to appear:
div id="displayNames"
and this is the call to the function:
input name="GetSurveys"
style="width: 103px"
type="button" value="View all surveys"
onClick=getSurveyNames();
Due to same origin policy restrictions you cannot send AJAX requests to distant domains, so this cannot work unless the page containing this javascript is hosted on http://survey-creator.appspot.com
. I suspect that you are trying to fetch an XML document which is hosted on a different domain which is impossible.
If you want to do this you might need to use a server side script on your domain which will do the remote call to fetch the XML and then return this XML so that your AJAX call invokes this server script:
$.ajax({
type: "GET",
url: "/myscript",
...
});
It looks like (based on the code snippet) that you have two cases where the order of });
and }
lines were reversed.
Did you take stuff out when you posted? If not then see how when formated correctly these problems become clear.
