JavaScript - How To Return Php Values To Javascript (for 'ajaxfileupload')
Hi there,
I am trying to build an interface to upload files and change some of the form (hidden) values depending on the file uploaded, here is where I got so far: Code: $('#buttonUpload').click(function (){
$.ajaxFileUpload({
url:'doajaxfileupload.php',
secureuri:false,
fileElementId:'fileToUpload',
dataType: 'txt',
success: function (data, status){
alert("File is uploaded,");
if(typeof(data.error) != 'undefined'){
if(data.error !=''){ alert(data.error); }
else{ alert(data.msg); }
}
document.getElementById('buttonUpload').style.color="green";
document.getElementById('isfileuploaded').value="green";
},
error: function (data, status, e){ alert(e); }
});
return false;
});
My problem is that I want doajaxfileupload.php to return a variable to javascript/change some html form value. The code works as it is for the file upload, I just need to add something for the output, any suggestion? Edit: I just noticed that some previous part of the code is still the the part that changes the color of the button depending if the file is uploaded or not. Now I want those values to change depending on what file is uploaded. Similar TutorialsHi, I've a Javascript function where i'm sending an return value. How do i capture this return value from HTML. My javascript func is as below: Code:
function check()
{
var frm=document.forms.stream_selection
sel_num = new Array();
Parr = new Array();
for(j=1;j<1000;j++)
{
if(frm[j] != null)
{
if(!frm[j].checked)
{
frm[0].checked=false
}
else
{
Parr.push(j);
ParrStr=Parr.join(',');
alert(Parr);
}
}
}
return(ParrStr);
}
My HTML call function is as below: Code: echo "<td><center><input name=\"sstreamname\" type=\"checkbox\" onclick=\"check():return true;\"></center></td></tr></font></center></tr></font></center>"; How do i get the value of ParrStr and transfer this to next form. I'm using PHP . Thanks, Ramki. Ok, guys. I'm new to JavaScript, so go easy. I'll be asking bunches of "dumb" questions for a while. 1st question, and the only one for now ... Say I have the following function: Code: function SwapValues(SwapVal1,SwapVal2)
{
TempSwapVal=SwapVal1;
SwapVal1=SwapVal2;
SwapVal2=TempSwapVal;
}
I don't care about the return value of the function itself, but I do need the new values of SwapVal1 and SwapVal2. In ASP when I do this, the values get returned. How do I get this to work in JS? This has me completely stumped. I have a multiple select form element in my HTML document that needs to be manipulated by two different sets of context-sensitive controls. One set of controls is marked up as follows: Code: <div id="divControls1" name="divControls1" style="display:none"> <form id="fControls1" name="fControls1"> <input type="button" id="btnAdd" name="btnAdd" value="Add" onClick="addStuff();" /> <input type="button" id="btnEdit" name="btnEdit" value="Edit" onClick="editStuff();" disabled /> <input type="button" id="btnDelete" name="btnDelete" value="Delete" onClick="deleteStuff();" disabled /> </form> </div> When I load this page into Safari (on Mac OS X) and set the style of divControls1 to "display:block," I have an enabled "Add" button, a disabled "Edit" button, and a disabled "Delete" button, just as I expected. (I monitor selections in a multiple selection element to turn the buttons on and off.) But when I load this page into Firefox (also Mac OS X), all three buttons are disabled at startup. My page runs a function called startup() when the body fires onLoad. To try to troubleshoot the problem, I wrote this line at the beginning of the startup() function: Code: function startup() {
alert (document.getElementById("btnAdd").disabled);
...
When I run this code in Safari, the alert returns "false" (not disabled), just as I would expect, and intended. However, the same code in Firefox (Mac OS X) returns "true" (disabled) ... but the same code in Firefox (WinXP) returns "false"! Any insight into what might be happening here? hi, i wanna get the value from javascript to php variable. here is my code, <html> <body> <select name="drop" size="10" onchange="drp_selectd_value(this)"> <option>One</option> <option>Two</option> <option>Three</option> <option>Four</option> <option>Five</option> </select> <?php echo "The PHP value".'<script>value_return();</script>'; $p='<script>y;</script>'; ?> </body> </html? <script> var x; var y=100; function drp_selectd_value(sdf) { x=sdf.value; alert("Value is : " +x); value_return(x); } function value_return(val) { alert("Second Function calling : "+val ); return val; } </script> This code does not working!!! How can i fix tis problem???I m expecting for the reply.. Thanks in advance i have this line of code: Code: <a href="#" id="profilelink" name="link2" onClick="viewornot(<?php echo $freechat_id ?>)"><?php echo $freechat_list; ?></a>
//call the JS onclick and if OK was click do the message box and send button here
then i have my JS: Code: function viewornot(id)
{
var e = confirm('Do you want to view this profile?');
if (e == true)
{
window.location.href = "http://www-rainbowcode-net/apps_dev.php/profiles/showprofilepersonal?id="+id;
window.location('http://www-rainbowcode-net/apps_dev.php/profiles/showprofilepersonal?id='+id);
return true;
}
else
{
var e2 = confirm('Do you want to send a message?');
if (e2 == true)
{
//if ok was clicked send value back??
return e2;
}
}
}
on the e2 confirm: if i clicked OK how can i send a value back(so that i know OK was clicked) so that i can then produce the message box and send button and do the rest of the code to send a message??? thank you Its a ads rotation code: Don know why it doesnt work... Code: <body>

here go(k); function might do this mass (output-->NaN). plz b a help... The website I'm updating is peachbasketonline.com. I am not the original web designer. I'm trying to reach an install page that is located in the directory, but anytime I go to a page outside of the site navigation (i.e. part of site navigation: About Us works fine, versus a page outside of site navigation: peachbasketonline.com/anythingelse) it automatically takes you back to the home page. Is there enough info here for someone to tell me if javascript is doing this? I just don't know what I'm looking for. Hello, I made a little code for my website but it doesn't work and I can't find out what the problem is. The problem is that the line return 2; does return undefined and not 2 as expected. I also tried to replace var xmlhttp2 = ''; for var xmlhttp2 = null; but it still not work. Does anyone know what is incorrect? Thanks in advance, PHP Code: function get_image(url) { var xmlhttp2 = ''; xmlhttp2=GetXmlHttpObject() xmlhttp2.onreadystatechange=function() { if (xmlhttp2.readyState == 4) { return 2; } }; xmlhttp2.open("GET", 'image_print.php?url=' + url, true); xmlhttp2.send(null); //return output; } I tried to use the script to return the user to the previous page by clicking the link, and it did work, however, it would return me to the previous website I visited and not just the previous page within my site. Is there a way to override it by changing the code or is the code definitive? This was the code I had tried to use: Code: <a href="javascript:history.go(-1)">Back</a> I don't understand the logic of Break, Return False, Return True. It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi all, Please keep in mind: this is the first code I have ever written -- much of it with help from this forum and the skeleton from other corners of the JS community. Thanks! But now for the problem... I'm developing am income tax calculator, and everything is going swell. Currently the user can type in their adjusted gross income (AGI), hit submit, and learn the amount of income tax they would pay, their tax rate, and their income after tax. I've played around with the events to get the submit button to work in FF, IE, Chrome and Safari -- and I've gotten the enter button to work before with some stock code, but here's the catch: when the user presses enter, i want the focus to leave the input box. I don't care where it goes (submit button, I suppose?) but i need it to leave the input field so the onfocus="clearText(this);" event can fire when they return to type in a new income. Any ideas? Thanks in advance. Code: <script language="javascript" type="text/javascript">

I do not know much about the compilers or how these things run. I do however have a good eye for trends and can figure just about anything out by looking at it. With that; I have a game that uses a exe launcher with a built in patcher. I have found the code for the launcher. There are several "jquery" scripts for basic components like scroll wheel. There are also things like "downloader.js", "inputs.js". I am interested in seeing what (and more precisely how many) ip addresses are being retrieved. I fear this patcher is using a hidden bittorrent like download system. The code for "downloader" is pretty basic. It clearly uses some other script, but I am wondering if you can point me in the direction of a utility to monitor running JS so that I can see what is being returned. Code: _Downloader = function()
{
this.downloadStatusCallback = null;
}
_Downloader.prototype =
{
setDownloadStatusCallback: function(callback)
{
this.downloadStatusCallback = callback;

I have tried on several occasions to teach myself programing. I can get the commands and syntax fairly easily, and I am pretty good at 'coming up' with ways to get something done. I just don't have experience in this field (I'm in medical school) so I do not know about the tools and utilities programers use and scouring the internet has been less than fruitful. Anybody capable of pointing me in the direction of finding a utility to monitor running js (if that is even possible =/). I use dreamweaver CS5 to explore js code. hi, (JAVASCRIT) the actual program reads and prints values from a checkbox tree and this piece of code does it. Code: dhtmlXTreeObject.prototype.getAllChecked=function(){
return this._getAllChecked("","",1);
}
dhtmlXTreeObject.prototype.getAllCheckedBranches=function(){
return this._getAllChecked("","",0);
}
dhtmlXTreeObject.prototype._getAllChecked=function(htmlNode,list,mode){
if(!htmlNode)htmlNode=this.htmlNode;
if(((mode)&&(htmlNode.checkstate==1))||((!mode)&&(htmlNode.checkstate>0))){if(list)list+=","+htmlNode.id;else list=htmlNode.id;}
var j=htmlNode.childsCount;
for(var i=0;i<j;i++)
{
list=this._getAllChecked(htmlNode.childNodes[i],list,mode);
};
if(list)return list;else return "";
};
the values are returned to alertbox. Code: <a href="javascript:void(0);" onclick="alert(tree2.getAllChecked());">Get list of checked</a><br><br> kindly help me with reading the returned values in to an array or list (but bot in alertbox) ...so that i can pass them to next JSP page. waiting for ur answer, BeanBoy ! I wasnt sure where to put this one, since its mainly javascript I thought I would put it here. I am trying to pull a value being stored in a php function (it works fine) which is echoed into an html element, and use it in a javascript function. my HTML: Code: <img id="menu_image" src="<?php echo get_php_value(); ?>" width="356" /> my javascript: Code: function get_large_image(){
