JS Call To PHP To XML File Back To PHP And Then Back To JS?
Mar 16, 2010
I have been trying to utilize a pre existing snippet of JS that makes a call to some PHP, where the PHP echo's out the answer, namely a dynamic quick search output, that gains its data from an xml file (which works as expected) and thought I might be able to rework the code to work for my altered purpose (which has been a disaster at every attempt) which is as follows:
1. I have a JS file called call4section.js - JS that has a string (str) value assigned (could be number or a combination of numbers and letters) which is passed to a PHP script called call4section.php.
2. The PHP script takes receipt of the string and finds a match within an XML file for the entry under <reference>.
3. The XML file has a format as follows:
<pages>
<note>
<section>value</section>
[code]....
And well, I dont seem to be able to get any further forward with it. Effectively, I can echo out the $reply (if it worked I think), but my stumbling block is sending the starting string, with the JS expecting some reply sent from the PHP.
I have just started learning JQuery and have a doubt in the below code. $.get('myhtmlpage.html', myCallBack);The doubt is should the 1st parameter of the get function be a HTML file or can it be a unction name?
I'm looking to have a lightbox pop up when a user clicks the Back button in their browser rather than just navigating back. The purpose is to ask a question with a Yes/No answer, and if they click No, I allow them to go back. The only thing I've found anything like this is the onUnload event, but that doesn't prevent them from going back. How should this be handled?
I am trying to write a script that uses the IF statement to see wether or not a user clicked the back button to come to a page, and then if it's true to not let the page load and kick them back X number of pages (say 4) This is what I have so far:
But /*THIS*/ and /*THAT*/ never happen. Is there a way of doing a callback, so that when the background image has changed, do the below functions. Then end with changing it to nothing again?
is there any way, using javascript, to call a function when someone presses back or forward in their browser? I'm using AJAX and have a partial solution. It works but would be more efficient if this is possible.
I have a webpage popup (lets call it POPUP) which refreshes the opener window (this one we call PARENT) when we close it, saying we want to save data. For this, we use
top.oWndOpener.refresh();
When we don't want to save the POPUP data, we just close the popup and don't refresh the PARENT. In the PARENT we have a "Back" link which executes a simple
history.back()
The problem is: If we refresh parent, we need to go back 2 pages, because the refresh method adds another page to the history. But we have no (easy) way of knowing in the PARENT if it had been refreshed. With this, our users are forced to click two times in the Back link.
Is there anyway of going back to the previous page, no matter how many refreshes happened in the current one ?
I want to bind a hook to objects member variable change event i.e. lets say I have object: var obj { var1 : 1, var2 : 2, var3 : 3 };
I want to call "Magical" function like this: onVariableChange(obj, "var1", function(obj, varname, old, new) { alert("Variable " + varname + " changed from " + old + " to " + new);}); And after this function call every time obj.var1 is set to some value have my callback function called
I found something in internet: [URL]. Its cool but: -It is changing Object-s prototype -It is not working under IE 5, 6, 7, 8, 9, 10, 11, 12.... I've changed it a little bit and instead of adding to Object class prototype I'm adding it as member to any object which needs this hook. But IE still doesn't work. Is there any known cross-browser solution for this? I remember there was a jQuery upcoming project which would allow users to bind object to form and by changing one other will change automatically I wonder whats that project name and how they change input value when object member value changed.
I'm trying out uploadify to upload images & files. Got it all working fine and got it so that it inserts the filename as a hidden form element so I can grab the filename on post and insert into the database -
But I want to rename the file in uploadify.php and pass the renamed value back to the form, so far, I can only get it sending back the original file name.
Looking to parse the XML file a perl script sends back.I wantto get values from specific tags in the XML file. Here is my code:
[Code]...
The code seems to be getting hung up on the dataType: "xml", line because when I comment it out, it goes to the next step and executes the function (although it doesn't do anything). how I can change this or just take a different approach? Let me know if I can provide more information.
I am trying to capture the back button and redirect if it is a certain URL, if not just go back like a normal back button.I've never really messed with the history except for something like this: <a href="#" onClick="history.go(-1)">Anyone have an example using this plugin: [URL]r any other plugin that might achieve this
I am doing a JSON request to get data back from a PHP file. On the return of that data, I am using a for loop to go through the data and post it up using JS. Here is my code:
for (var x = 0; x < data.length; x++) { //create a container for each comment var div = $("<div>").addClass("entry round").appendTo("#characters"); //add author name and comment to container $("<div>").addClass("details").appendTo(div); $("<span>").addClass("main-armory button").appendTo("div.details"); }
Now, what is happening, because there is 10 entries being posted, my JS is looking at the class that is being put together (main-armory button) and making it so that class appends every run through. So, I want one entry for main-armory button and I am getting this:
And then, when it goes down to the next entry, it has 9 spans, and then the next entry has 8 spans, and it continues all the way down. What is going on here that I am missing? I know that I am not clearing a variable properly or something is wrong within my loop.
I am wondering how Back, Forward browser button works for iframes. Does it bring back/forward iframe or top window? I remember I had before a problem because I wanted to bring back iframe and not top window as it did. But today I tested my Facebook app and was surprised to see it works as I need which means it brings back/forward iframe window and not top. Is it possible that Facebook has some javascript code which does that or is this normall behaviour?
I can use the following code to create an HTML table based on an XML document. However, I would like to pass the onreadystatechange event a callback function (with arguments) to process the XML document. This way I can effectively remove the processing of the document from the event handler.Alternatively, is there a way the event handler can return a reference to the document, so that I can then parse it externally to the event handler?
Code:
function LoadXMLDoc(url) { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest();
I have a form with a "Print" button on the page. When the user clicks this it doesn't actually print but opens a condensed version of the page, passing the field contents with php. On the new (condensed) page I capture the load of the page in js and when it occurs issue the command print(). This works fine.
But once I've done this (printed) I would like to return to my original form. I've tried
if (print()) history.back()
print() history.back()
neither seems to work. As an experiment I put the following code at the bottom of my condensed page that prints...
<FORM> <INPUT type="button" value="Click here to go back" onClick="history.back()"> </FORM>
Clicking on the resulting button does exactly what I want... clears the form and returns me to my original.
I just don't what to a) print the form with that button on it b) require user input after the printing.
So... can anyone point me in a way of making history.back() work outside of an onClick construct?
I used <input type="button" value="Back to Correct" onclick="window.history.back();"> to go back to the previous page is working, but if i use the as below instead, it does not work. what did I do wrong?
I have a graphic with a rollover for site navigation on each page. I put the page to go back to in the rollover javascript.
My question is, is it possible to put in some code that will refer the visitor back to whatever page they came from rather than one I specify?
The rollover is combined with a tooltip script to make matters fun (below). However, I'm quite happy to lose the tooltip to have the link perform as a back button.
<a href="../index.asp" onmouseover="document.images['link1'].src=img2.src; showtip(this,event,'Back to home page');" onmouseout="document.images['link1'].src=img1.src; hidetip()";><img src="bhome.gif" name="link1" border=0></a>
