I have a file list, when the user double clicks a file, it is displayed in an editor,
The problem is, after opening a javascript file, all bootstrap functions get undefined.
UPDATE:
function openFile(file){
var filename = file.getPath();
$.ajax({
url: "${fileStorageServiceBaseUrl}" + applicationId + "/files/"+ resType + filename,
type: "GET",
success: function(response) {
editor.setFile(filename, response);
}
});
openResType = resType;
$("#saveButton").prop("disabled",false);
}
After calling this function, bootstrap functions get undefined. I'm calling it from the console, not via events now.
function openFile(file){
var filename = file.getPath();
$.ajax({
url: "${fileStorageServiceBaseUrl}" + applicationId + "/files/"+ resType + filename,
type: "GET",
dataType: "text", // THIS LINE SOLVED IT!
success: function(response) {
editor.setFile(filename, response);
}
});
openResType = resType;
$("#saveButton").prop("disabled",false);
}
From the jquery documentation:
dataType: (default: Intelligent? Guess (xml, json, script, or html)) Type: String.
The type of data that you're expecting back from the server.
"script" (this was getting selected by default): Evaluates the response as JavaScript and returns it as plain text.

I need to pass data from HTML page to PHP page But without data callback ....
i'm used two method but One of them did not succeed
1)
$.ajax({
type: "POST",
url: 'phpexample.php',
data: {voteid: x },
success: function(data)
{
alert("success! X:" + data);
}
});
2)
$.post("getClassStudent.php",
{
},
function(data){
$("#div_id.php").html(data);
}
);
as i can understand, you just want to send info to a php script and don't need the response, is that right?
try this
$.post("phpexample.php", {voteid:x});
or simply remove the "succes" function from the equation if you feel more confortable using $.ajax instead of $.post
$.ajax({
type: "POST",
url: 'phpexample.php',
data: {voteid: x }
});
your fisrt example is correct, the second is not well formed.
more info:
http://api.jquery.com/jquery.post/
EDIT: to help you some more :)
<button type="button" id="element-id">click</button>
<button type="button" class="class-name">Click</button>
$(document).ready(function(){
//if you are marking ans element by class use '.class-name'
$(".class-name").click(function(){
$.post("getClassStudent.php");
});
//if marking by id element use '#id-name'
$("#element-id").click(function(){
$.post("getClassStudent.php");
});
});
be carefful with the markings, for debuggin try to use "console.log()" or "alert()" so you can see where is the problem and where the code crushes.
var formData = {
'voteid' : 'x',
};
$.ajax({
type : 'POST',
url : 'phpexample.php',
data : formData, // our data object
dataType : 'json',
encode : true
}).done(function(data) {
console.log(data);
});
I have a performance problem when loading a website over the network stored on an internal server. The performance issue is down to the multiple AJAX requests made in my Javascript file constantly trying to access an XML file and then getting an Image from a XML node or a Name from an XML node.
Is there a way I can merge the AJAX requests together to reduce the amount of requests from the client device to the XML file stored on the server.
My code is as below:
function getimage(getID,XMLImageID)
{
$("#" + getID).empty();
$.ajax({
type: "GET",
url: "XML/XML.xml",
dataType: "xml",
success: function(xml){
$(xml).find(XMLImageID).each(function(){
var image = $(this).find("image[href]").attr("href");
$('#'+ getID).append($("<img"+" class="+"Timages"+" src=\"" +image+"\"/>"));
});
},
error: function() {
alert("(getImage) An error occurred while processing XML file. Reasons could be: \n The XML cant be located. \n The XML is being used by another program. \n The XML is trying to parse incompatible characters. \n The XML syntax/tags are incorrect.");
}
});
}
function getdept(getid,XMLID)
{
var scriptTag = document.scripts[document.scripts.length - 1];
var parentTag = scriptTag.parentNode;
getid = parentTag.id;
$.ajax({
type: "GET",
url: "XML/XML.xml",
dataType: "xml",
success: function(xml){
$(xml).find(XMLID).each(function(){
var dept = $(this).find('Dept').text();
var id = $(this).attr("id");
var sName = $(this).find('Name').text();
$("#"+getid).append('<div class="Team_People" onmouseover="area_hover1(this);area_hover2(this)" href="#p'+id+'">'+dept+'<br />'+sName+'</div>');
});
},
error: function() {
alert("(getHierPeopleDept)An error occurred while processing XML file. Reasons could be: \n The XML cant be located. \n The XML is being used by another program. \n The XML is trying to parse incompatible characters. \n The XML syntax/tags are incorrect.");
}
});
}
The AJAX response uses a simplified code below, I just need to merge the code above to make it more neater rather than having multiple ajax requests. Not sure if this is possible (whether adding multiple parameters would work)?
$.ajax({
type: "GET",
url: "XML/XML.xml",
dataType: "xml",
success: function(xml){
$(xml).find(XMLID).each(function(){
//Get something from XML node
});
},
});
}
If anyone could guide me in the right direction that would be much appreciated!
Thanks

Create a global XML variable and query that with your function calls...
var XML = null;
function fetchXML(){
$.ajax({
type: "GET",
url: "XML/XML.xml",
dataType: "xml",
success: function(data){
XML = data;
},
error:function(){ alert('something went wrong');})
}
function getImage(id) {
$(XML).find(id).each(){ ... };
}
funcition getDept(id) {
$(XML).find(id).each(){ ... };
}
I have this function that performs a GET request for a given id:
var findById= function(id) {
console.log('findById: ' + id);
$.ajax({
type: 'GET',
url: rootURL + '/' + id,
dataType: "json",
success: function(data){
console.log('findById success: ' + data.name);
currentRaceEntry = data;
renderList(currentRaceEntry);
}
});
};
When I enter sitename/rest/entries/8 it returns a page with the xml for the object requested(as expected). (I can show this code but I dont think the problem is there). When I preform this request the console shows:
findById 8
My question is why doesn't it show console.log('findById success: ' + data.name);? The xml displays in the browser which looks to me like it was successful. So why doesn't the success function appear to be called? Thanks!
EDIT
this is what it looks like:
The console in the browser is blank
If you ajax request returns XML data, you need to set dataType as "xml".
At that point, the data object in the success function is an XML fragment, not a javascript objet, and you need to process it as such. The data.name property doesn't exist.
I have this URL, that I supposedly should receive an XML from. So far I have this:
function GetLocationList(searchString)
{
$.ajax({
url: "http://konkurrence.rejseplanen.dk/bin/rest.exe/location?input=" + searchString,
type: "GET",
dataType: "html",
success: function(data) {
//Use received data here.
alert("test");
}
});
Tried to debug with firebug, but it doesn't go into the success method.
Though, in DreamWeaver it is able to post a simple alert, which is inside the success method.
I tried writing xml as dataType, but it doesn't work (in DreamWeaver) when I write alert(data).
But it shows an alert with the entire XML, when I write html as dataType.
How do I get the XML correctly, and how do I parse and for example get the "StopLocation" element?
Try to add an Error function as well.
See enter link description here
This will give you all the informations you need to debug your code with Firefox.
$.ajax({
url: "http://konkurrence.rejseplanen.dk/bin/rest.exe/location?input=" + searchString,
type: "GET",
dataType: "html",
success: function(data) {
//Use received data here.
alert("test");
},
error: function(jqXHR, textStatus, errorThrown ){
// debug here
}
});
you need to parse it first, and then you can search for the attributes. like this.
success: function(data) {
var xml = $.parseXML(data)
$(xml).find('StopLocation').each(function()
{
var name = $(this).attr('name');
alert(name);
}
);
this will give you the name of each StopLocation.
hope this helps, you can use the same method for all other attributes in the document also.
I have one problem with function in Javascript. When I insert text in textarea, function sends text to PHP script with AJAX, but I have problem when I insert two or three words, e.g Bosnia and Herzegovina then the script does not work. I used string replace :
function provjeraDrzave(rijec) {
rijec = rijec.replace(" ", "%20");
$.ajax({
type: "GET",
url: "/drzava.php?slovo=" + randomslovo + "&drzava=" + rijec,
success: function (odgovor) {
$('#rezultati').replaceWith($("<span id='rezultati'>" + odgovor + "</span>"));
},
error: function () {
alert('Doslo je do pogreske');
}
});
}
It should work as follows: When I insert Bosnia and Herzegovina that must change to Bosnia%20and%20Herzegovina but that change to Bosnia%20and Herzegovina and that does not work. Where is the problem ??
Why don't you use, for example, the native encodeURIComponent function, which is made for this?
Or, even better, let jQuery take care of URL encoding for you, using the data config param:
function provjeraDrzave(rijec) {
$.ajax({
type: "GET",
data: {
slovo: randomslovo,
drzava: rijec
},
url: "/drzava.php",
success: function (odgovor) {
$('#rezultati').replaceWith($("<span id='rezultati'>" + odgovor + "</span>"));
},
error: function () {
alert('Doslo je do pogreske');
}
});
}
jQuery $.ajax can receive url arguments via the data property and should automatically serialize it for you.
data
Data to be sent to the server. It is converted to a query string, if not already a string. It's appended to the url for GET-requests... Object must be Key/Value pairs...
$.ajax({
type: 'GET',
url: '/drzava.php'
data : {
'slovo' : randomslovo,
'drzava' : rijec //no need to replace
}
success: function (returndata) {...},
error: function () {...}
});
If you absolutely want to do this way try
rijec = rijec.replace(/\ /g, "%20");
but encodeURIComponent would be more appropriate.
