Ajax :: Return Xmlhttp.responseText From Function?
Jun 9, 2011
I've been racking my brain for a couple hours now and doing a lot of searching and I cannot seem to find an answer. I want to know if it is possible to return the xmlhttp.responseText value from an AJAX function to the function that originally called the AJAX function.
Code:
//Set handler for server response.
xmlhttp.onreadystatechange = function()
{
[Code]....
I want to return the my_response variable to the original caller. No matter what I try I have been unsuccessful. I even tried assigning it to the global window variable using window.my_response = xmlhttp.responseText but it ends up being undefined.
Every example I've seen of using AJAX pretty much does something inside of the if (xmlhttp.status == 200) part to update the web page. I really do not want to do that.
Code: var request = new XMLHttpRequest(); request.open("GET", "http://127.0.0.1/get/file.json?filepath=c:\xxx.xxx"); request.onreadystatechange = function() { if (request.readyState == 4) {
[Code]...
using above code, I wanna implement uploading/dowloading/parsing file with json format. however, the responseText always return null in FF. It it about to make me crazy.
how to Get xmlHttp.responseText when you call from IFrame? I get empty xmlHttp.responseText, while when calling server from out the IFrame, I get the responseText without problem, how can I solve this problem?
I'm working on a script that calls my php file, checks the db and returns text. If the returned text="bad" then i want the var "bad" to be set to 1. at the bottom of my script, if anything has tripped bad=1 then it returns false and the form doesn't submit...everything works great except for this one piece so i was wondering if you guys might offer me some insight
I need to turn xmlhttp.responseText into a column of links that will be displayed in a popup div.I've defined xmlhttp.responseText as var named txt with: var txt=xmlhttp.responseText;
That produces a var with comma delimited values. I'd like to proceed by passing txt through a For Loop that will create the links, but I can't find a method that will count commas.
How do I return the number of commas in javascript?
i like to access a PHP file do some work and then if all is successful return the response text update the div innerhtml compare div content with xmlhttp.responseText
I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"
I'm not too good with programming, but I'm trying to get my feet wet with some nice little AJAX tools. I have some things currently working, but I'm trying to re-write the code so I can reuse these modules for a number of functions....As of now, I have a function that returns XHR requests [ ajaxRequest(){} ]. I am calling this function inside an XML Parser called [ ajaxParser(){} ]. Once that's created, I have the following code:
Code:
xmlDoc = new ajaxRequest() xmlDoc.onreadystatechange = function(){ if (xmlDoc.readyState == 4){ if (xmlDoc.status == 200){[code]....
At this point, I want the function to return an object that holds all the XML Node names, lengths, textContent, etc. I would like to be able to call this in any other function I write and begin traversing the nodes there. Something like root = new ajaxParser(file.xml);I tried "return parentMenuList;" except the length return is undefined. What I see in the DOM inspector is an object called root (with no other properties to it).
I am attempting to use the return value from a nested ajax function as the value for a variable in its parent. However, despite being able to successfully assign the variable within the nested function, it reverts back to its original value after the child function has terminated. Below is the code:
I am having a problem of calling the user defined JS function after I make the AJAX call. Basically, I created couple radio buttons on the main html page. When the user clicks on one of the radio button, it will trigger the AJAX call and return another html file in the "div" content that I set in the main html page. The other html file contains a user defined JS function (e.g. "updateContent()") which use the onclick event handler to call the function. When I'm running the app, and click on the button. I had seen the firebug was complaining the "updateContent() is not defined" error. The function itself works fine and must be defined properly.
Here is the code in the main.html page:
Code:
<script type="text/javascript"> var asyncRequest; function getTools(url){ try

I'm making an ajax call to return the contents for a page using the responseText property. I want to be able to define a javascript function in the page and call it, doing something like:
<script> function test(){ alert('hi'); } test(); </script>
However, none of the javascript in my page works. I'd imagine it has something to do with it being included as part of the responseText and the browser is not picking it up. I haven't been able to find any info about this online anywhere. Any thoughts?
if it's possible to return an array from my php generated content to ajax's responseText. I tried echoing back the whole array variable but can't seem to fully receive it in javascript.
I am trying to read data from server using AJAX XMLHttpRequest.responseText.In received data, there are lot of similar type of characters which has tge value of FFFFFD (65533). I think, all characters which has the value above 127 are converted to default character.
I have a periodicalUpdater that returns countdown time that is created with php but I now need to call out one function when the time is right. the script PeriodicalUpdater calls
I am wondering how can I return the variable senttext from the function below?I have declared it and when I alert(senttext) below it appears as I want it but I need to return it and pass it to another function. When I change alert() to return the variable becomes undefined?
var senttext; function getData() { if (window.XMLHttpRequest) {
I am trying to use AJAX and JSON to do this. I have copied an example of using HttpRequest Object as the backbone of this from http://www.w3schools.com/dom/dom_http.asp. Further, I am enclosing both of my files here, in full as opposed to mere snippets. This code does what I wish it to do except:
1. It does not update when getdata.php is rewritten. On non MSIE broswers, it shows when first invoked, but not subsequently. 2. It fails altogether under MSIE (6.026 SP1 || SP2) -- I never get xmlhttp.readyState==4 under MSIE.
In firefox, i look through the DOM and its showing me that both xmlHttpRequest and ActiveXObject("Microsoft.XMLHTTP") are undefined.Also if one could check the ready state methods I used, I'm not 100% if they are correct eg. xhttp.onreadystatechange = loadBlurbs() and if null is the value for a failed loading procedure.lasty, can I do this processBlurbs() = getElementByTagName, and then, processBlurbs() { this.length, this.child etc. ? }
Code: <script type="text/javascript" language="javascript"> var blurbdoc; var blurbs;[code].......
I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?
i've got a function which makes a call to the database( via jquery $.post) to check if a username already exists. All the data I get back is fine and both the conditional statment works as intentded. I just can't get the function to return a value to the other function that calls it. Could this be something to do with the scope.
