Get And Eval() Inner In Script Tag From AJAX Call?

Oct 26, 2011

I have an AJAX call to a data grid. The datagrid is authored by Advanced Power of PHP [URL]

I don't want to get crazy and modify the data grid to give me different responses back but rather when it sends a response like this back to the browser via AJAX:

HTML Code:
<form name="frmPagingUpper" id="frmPagingUpper" action="" style="margin: 0px; padding: 5px;"><table class="blue_class_paging_table" dir="ltr" style="margin-left: auto; margin-right: auto; width: 90%;" border="0"><tbody><tr><td class="class_nowrap" align="left"></td><td class="class_nowrap"

[Code]....

JQuery :: Eval Fails In Ajax Call?

Dec 4, 2010

I'm working on a weather api. A call to an internal PHP page GETs XML and returns JSON. However, I cannot get it to evaluate as an array:

(function($){
$.ajax({
type: "GET",
url: baseUrl + "weather_data/get_forecast",

[Code]....

Firebug (FF 3.5) displays the response in the JSON tagged perfectly parsed, but the code above fails.

AJAX :: Eval Works On FireFox But Not On Google-Chrome?

May 28, 2011

While doing simple interactive mathematical calculator for my son, i came across some issues. in the beginning i was working on Firefox 4.0.1 Fedora 15 didn't get any issue yet when i switched for google-chrome 11.0.696.68 the script didn't work anymore. i trimmed it down to simplest form possible and here i demonstrate:

<html>
<body>

AJAX :: Call Based On Results Of A Previous Call

Dec 14, 2010

The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.

Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.

I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)

AJAX, Eval(), And Javascript Within Javascript

Apr 28, 2006

Ok so, this is my purpose:
- to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML

Why?
-Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering

My problem:
Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed
For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')"
if I use xxx.innerHTML=text, nothing happens

My 1st solution:
Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt):
if I eval the code, it deletes my current page and renders a new one
for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text

What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML

Is this even possible? How would you go about it?
I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...

webservice returns a Dataset that contains various customer details

AJAX :: Checking DOM After Call?

Jul 31, 2010

I'm having a problem where a button no longer triggers an event after I changed it through an AJAX call.Problem is, once AJAX has updated the DIV, the contents in RAM is different from what I see when I check the page source (CTRL-U in FireFox/Chrome).What tools are there to display the current contents of the DOM? I generally prefer to use Chrome/Iron, but if there are better tools for Firefox, I'm also interested.

Ajax :: Call To PHP On Different Domain?

I wish to make an AJAX call to a script on a different domain - realise this is a security problem, but is this at all possible?

My client is embedding html web pages into his ebay listings, and he wants to centrally update the product information. Maybe there is a different / better way to go about this?

AJAX :: Call That Works In FF Not IE?

Jun 23, 2011

This code updates a feedback box every 5 seconds. Web page:

<body onload="fback();setInterval('fback()',5000);">(declared firstly so that you don't end up with a blank space for 5 seconds when the page loads.) This calls an XMLHttp request to feedback.php.

xmlhttp_fb.open("GET","feedback.php",true); The php page queries a table and returns one item from about 360 records by randomly choosing a UniqueID between 1 and the last row. I deliberately chose this because it's quicker than querying them all once and working through an array.

[Code]...

Enough code to give you the idea I hope. $max is the last row of the feedback table. (Found by ORDER DESC)

This works great in Firefox and Chrome but not IE7 or 8. Really can't think why because there are no setInterval issues that I know of.

JQuery :: How To Get UI Widgets Via Ajax Call

May 10, 2011

My goal is to get some HTML content including some UI widgets and other stuff via an ajax call. To clarify my goal and the strange behavior, I attached some HTML files, that you can run for yourself. Open the index.html will show you some UI widgets, which are pulled from the ajax.html via ajax. When you scroll to the bottom you can see the same content inserted a second time. But this time, the widgets are not "rendered". It looks if the "button()" calls etc. are not executed.

The only difference is the way I insert the result of the ajax call. The first time I insert the hole content received by the ajax call, the second time I only insert the content of a special div. The goal in this is to get various chunks of content with one ajax request and replace "div#one" and "div#two" with different parts of my site. Which is not working. Is it generally okay to receive html content which has some script parts to be executed via ajax and what is wrong with my second approach?

JQuery :: Cannot Return Value After Ajax Call

Aug 9, 2009

I'm currently using the dialog functionality (modal form) from UI library to submit data to the database. All the validation checks have been running ok until one of the validation checks requires a ajax call to check if a username exist in the database. I'm fairly new to both javascript and jquery so this could be a fairly basic blunder. Initially, i thought it was an synchronicity problem, but I changed the $.ajax async option to true but still no joy, so maybe it something to do with scope etc?

Here's the code:
function checkIfUsername(){
$.ajax({
type: "POST",
url: ""+CI_ROOT+"index.php/admin/check_if_username",
data: ({username: username.val()}),
async: false,
dataType: "json",
success: function(data){
returnUsernameBool(username, data);
}});
}function returnUsernameBool(o, data){
if(data.bool == true){
o.addClass('ui-state-error');
updateTips("Your username must be unique");
alert('false'); //this works
return false; //still can't return bool
}else{
alert('true'); //this works
return true; //still can't return bool
}}
bValid = bValid && checkIfUsername(username);
alert(bValid); //still gives undefined

Ajax :: Call To Database Before Closing Row

May 17, 2009

I have a table with a list of games in rows. I want the user to be able to close/hide the game they don't want to play. At the moment I am using this;

Code:
<script language="JavaScript" type="text/JavaScript">
function removeR(r){
r.parentNode.removeChild(r);
}
</script>
<table>
<tr>
<td>Game 1</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>

<tr>
<td>Game 2</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>

<tr>
<td>Game 3</td>
<td><input name="button" type="button" onclick="removeR(this.parentNode.parentNode)" value="Close" /></td>
</tr>
</table>

This hides the games the user doesnt want to see on the page. But before the game is hidden I want to make an Ajax call to the database and add the user's preference into the table so next time the user comes to the page I can hide the game from the start. How can I do this?
