JavaScript - Chrome: Refusing Ajax Parameters
Hey everyone, I'm trying to write a script that uses AJAX. So far, it is working in both IE and Firefox. Unfortunately, it doesn't seem to be working in WebKit browsers. Chrome's JS console is throwing errors such as "Refused to set unsafe header 'Content-length'" and "Refused to set unsafe header "Connection". Both these headers seem to be functioning properly in other major browsers.
Here's the AJAX code that is effecting it: Code: http_request.onreadystatechange = alertContents;
http_request.open('POST', url, true);
http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http_request.setRequestHeader("Content-length", parameters.length);
http_request.setRequestHeader("Connection", "close");
http_request.send(parameters);
Anyone know why this is occurring? Similar TutorialsI built a registration and edit profile form using java to show or hide drop down selectors dependent on parent selection. I'm also using an ajax script to pull the selector values from txt files for the city selector. This works fine in chrome, but will not work in ie or ff. I've also found that the ajax script simply doesn't work in ff at all period even with the formmanager scrip removed. The site is erecoverydev.com. Click on the join now tab to see the registration form, or you can log in with un test and pw test123, then click on edit my page in the left hand menu to view the edit profile form. Here is what's in the head to call these scripts: Code: <script src="/js/FormManager.js">

};

{

var val = dd1[idx].text;
var par = document.forms["adminForm"];
var parelmts = par.elements;
var cb_citysel = parelmts["cb_city"];
var state = val;
if (cb_state != "Select state")
{
var directory = ""+document.location;
directory = directory.substr(0, directory.lastIndexOf('/'));
Http.get({

callback: fillcb_city,

}, [cb_citysel]);
}
}
function fillcb_city(xmlreply, cb_cityelmt)
{
if (xmlreply.status == Http.Status.OK)
{
var cb_cityresponse = xmlreply.responseText;
var cb_cityar = cb_cityresponse.split("|");
cb_cityelmt.length = 1;
cb_cityelmt.length = cb_cityar.length;
for (o=1; o < cb_cityar.length; o++)
{
cb_cityelmt[o].text = cb_cityar[o];
}
}
else
{
alert("Cannot handle the Ajax call.");
}
}
</script>
Any ideas? I'll post the rest of the script codes in a reply. It works in Google Chrome but not Firefox and Internet Explorer. My computer has blocked Opera and I don't know how to change that. Too much energy to investigate now, I'll do so later. Are there any pros that can tell me why this is happening? I'm assuming GoogleChrome is fixing a syntax error that FF and IE don't. Code: var request;
request=false;
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}
function isAlNum(str){
return /^[a-z0-9]+$/i.test(str);
}
var preUsername;
var same;
function updatePage() {
if (username.value.length>0){
if ( request.responseText.indexOf("0") == -1 )
{userNameErrorBox.innerHTML=username.value + " has already been taken";
usernameSuccessBox.innerHTML="";}
else
{userNameErrorBox.innerHTML="";
usernameSuccessBox.innerHTML=username.value + " is available";}}
}
function nameTest()
{
if (username.value==preUsername)
{same=1;}
else
{same=0;}
if (!isAlNum(username.value))
{if (username.value.length>0)
{username.value=preUsername;}}
else
{preUsername=username.value;}
if (username.value.length>0 && username.focus && same===0)
{
userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";
request.abort();
var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
}
if (username.value.length===0)
{ userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";preUsername=""; }
}
I back tracked what i did and it appears that this code Code: var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
has the problem. When I set up alerts to see what works and what doesn't, this code seems to be causing the FF and IE to not work, but I can't tell what it is that's causing them to fail. This is javascript that is suppose to check if a name has been taken by another user. I'm working on a fairly large project that I wish to be the new formspring, (size wise) I procrastinated for 2 weeks of my 12 week break and now that I'm just getting started on it I'm running into an ishness load of problems... Very de-motivating Hey, I am using prototypes (library) ajax methods and one of them is properties. I am passing in the name value pairs: var itemFilter = "MajorCat: Shoes", parameters: { q : qry ,fq: itemFilter }, But when I request, it gives me this in the url: MajorCat%3AShoes That won't work, the search application on the backend doesn't filter properly because of the "%3A" instead of ":". When I manually pass in via the url: MajorCat: Shoes (at the end of the query) it works. So, that ":" is getting encoded. How do I get that IN the hash and make sure the request is unencoded when it goes out? thanks Hello, I am trying to use .innerHTML to replace an image with an embedded flash file. Here is my code... HTML: Code: <a href="#" onclick="funt1(); return false;">do it to it</a><br><br> <span id="embed"><img src="video%20convert%20zone/zerotime.png"></span> JavaSscript: Code: <script type="text/javascript">
function funt1(){
document.getElementById('embed').innerHTML='<object width="100" height="40"><param name="movie" value="video%20convert%20zone/video.swf"></param><embed src="video%20convert%20zone/video.swf" width="100" height="40" name="player" id="player" menu="false" loop="false" bgcolor="#000000" wmode="transparent" type="application/x-shockwave-flash"></embed><param name="loop" value="false"></param><param name="menu" value="false"></param><param name="bgcolor" value="#000000"></param><param name="wmode" value="transparent"></param></object>'; return false;
}
</script>
And for some reason in Internet Explorer when I click the "do it to it" link, the image just disappears, and object and embed don't appear. But it works in Firefox. Any suggestions? Since the upgrade from chrome 9 to chrome 10 my script is showing an error in my variables when i use boolean expressions. they changed to version V8, Chrome's JavaScript engine. Here is the function function get_form_value(n){ e=document.getElementById(n); if ((e.value)&&(e.value != "")&&(!e.options)) return e.value; if ((e.selectedIndex)&&(e.selectedIndex>0) &&(e.options[e.selectedIndex].value !="")) return e.options[e.selectedIndex].value; // select if ((e.text)&&(e.text.value !="")) continue; if ((e.selectedIndex)&&(e.selectedIndex>0) &&(e.options[e.selectedIndex].text !="")) return e.options[e.selectedIndex].text; // select if ((e.checkbox)&&(e.checkbox.checked)) return true; return false; } When i run it it shows a syntax error: Can someone please help me fix this? Hi, Could I stablish parameters to .html or .asp (principally) dealing with width, height, color, etc. like this? Quote: <ASP:FILE ID = "oApp" APPLICATIONNAME = "Drive coll and obj" BORDER = "thin" CAPTION = "yes" ICON = "/images/book.ico" SHOWINTASKBAR = "yes" SINGLEINSTANCE = "yes" SYSMENU = "yes" WINDOWSTATE = "maximize" SCROLL = "yes" SCROLLFLAT = "yes" VERSION = "1.0" INNERBORDER = "yes" SELECTION = "yes" MAXIMIZEBUTTON = "yes" MINIMIZEBUTTON = "yes" NAVIGABLE = "yes" CONTEXTMENU = "yes" BORDERSTYLE = "normal" > Best for now just he! Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. Code: function viewDetails(rowid,linkid){
alert("enterining into bundles");
if(linkid=='seobundles')
{
alert("enetering into if ");
document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeobundleW?rowindex="+rowid;
document.chwAnnouncementW.submit();
}
else
{
alert(linkid);
document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeoW?rowindex="+rowid;
document.chwAnnouncementW.submit();
}
}
Actually i am passing linkid="seobundles" as string but its not interpreting and it is always going to else part and not if part. I tried to print link id its teling its of object HTML table type and we are passing the two parameters rowid, linkid from a macro. rowid is working fine as and when we select radio buttion but linkid is not working as an string. IF i pur linkid in single quotes then also its not working Hi, I am making a function that executes code as AJAX readyState's are returned... If readyState = 3 then I running code through eval but I want to be able to run functions with parameters, within the parameter that is evetually executed by the eval Heres abit of pseudo code of what I am talking about Code: function receiveRequest(whileLoading, whenDone) {
// AJAX stuff... blah... blah... blah...
if request is being processed:
eval(whileLoading)
if request is done:
eval(whenDone)
}
// When a button is clicked:
onClick="receiveRequest('alert('loading')', 'alert('finished AJAX request')')"
But this doesn't work because I am escaping the first parameter of 'receiveRequest' in the alert() but if I use double quote (") I will be escaping the event handler Is there anyway to get around this / or a better way to fix it? I haven't used Javascript in agggeeesss and I can barely remember anything anymore - PHP <3 Thanks in advanced. i m trying to implement captcha in my site.i m using recaptcha. To check the captcha i need to request url like: http://www.google.com/recaptcha/api/verify?privatekey="key"&remoteip="ip"&challenge="chal"&response="res" and then i need to check response from url if it is true or false i dont know how to request response from url help plz I am to make a showresults function, purpose is for results 4 parameters are in function, race, name,party and votes i then declare variable named totalV equal to value of returned by the totalVotes() function useing votes as parameter value then write HTML code to document this is the code I came up with Code: function showResults(race,name,party,votes)
{ // script element to display the results of a particular race
var totalV = totalVotes(votes);
document.write("<h2>" + race + "</h2>");
document.write("<table cellspacing='0'>");
document.write("<tr>");
document.write("<th>Candidate</th>");
document.write("<th class ='num'>Votes</th>");
document.write("<th class='num'>%</th>");
document.write("</tr>");
}
How does this look so far? I need to create a function with named getFontSize() needs one parameter named "id" and id is value of object in document then to create a variable named object to represent object return font size of text in object use style object to retrieve font size and use parseInt() function to get value of font size this is the code i came up with Code: function getFontSize(id) {
// Returns the font size of the object with the value id
var object=document.getElementById(id);
fontsize=parseInt(object.style.fontSize);
return(fontsize);
}
What should i change to make work/ Hello, I have a question. If I include js like this: <script type="text/javascript" src="code.js?ver=1"></script> If this include makes browser to always download js script? or does he use script from catch? I need this for changing ver number for browser to know when to redownload script. maybe is other way to redownload js script just when js script content is changed? P.S. Sorry for my bad english. (I hope you understand what I wanted to ask) Regards, sAdFella Hi, I have a website with several pages. Each page having the same menu. I need one of this menu item's text to vary according to each of my customers, where the customer id will be passed from an external link at launch time. I also need to change the menu item link <a href.../a> dynamically. I'm planning to create a redir.html pacge for each client and within that page, I can insert a url with parameters to launch the main page. Any clue more than welcome! I am working on this simple calculator that passes values from one function to another via paramters. I have used alert() to find what is being recieved, so far nothing. here is my code: Code: <html>

alert("area: " + perimeter) // doesnt work
}
function calcPerim(l,w) {
var perimeter = 2*(l+w)
return perimeter
alert("perimeter: " + perimeter) // doesnt work
}
function calc() {
var width
width = document.calcForm.widthBox.value
var length
length = document.calcForm.lengthBox.value
alert(length + width) // works
calcArea(length, width)
document.clacForm.areaBox.value = area
calcPerim(length, width)
document.clacForm.perimeterBox.value = perimeter

Now, I could write a version of the keypress function for each rectangle, but that seems like poor coding. Can anyone point out how I might restructure the function or the code so that I can pass the number in the onClick to the rectangle it refers to? Thanks Hi, Is there any way to use the activeX to execute a local aplication with parameters... Example: PHP Code: <script> var ws = new ActiveXObject("WScript.Shell"); ws.Exec("c:\\windows\\notepad.exe"); </script> I am passing parameters from one page (actually from a frame within a frameset) to another using Javascript. Typically the code is as follows, taking values from a Form. Code: parent.titleFrame.location="frm_right_demo_title.html?MyDateEvent.value='"+ytt+ "'&MyParam_spec.value='"+parent.mainFrame.document.forms.myForm.MyParam_spec.value+"'"; This has worked fine in all browsers including IE, Chrome and Firefox version 2.0.0.2. However, I have now found that it doesn't work with Firefox version 3.6.12. This is because when retrieving the parameters in the new loaded page, the character ' (quote) has been converted to %27 (percent twenty seven). I can write code to replace %27 with the quote character. However, this is lengthy and time-consuming (as I need to have cyclic code as the javascript replace command seems to work only on the first occurrence within a string). Can someone please help me to understand why this is happening and how to overcome it? Hi, This is a noob question which I've searched all over for but can't find an answer..........which means it probably isn't possible Can I pass a parameter to a javascript function from embedded javascript? I have a function in a separate .js file which accepts a parameter as follows: function initialize(menu){ alert(menu); } When I use the following javascript embedded in my HTML it doesn't work: <SCRIPT LANGUAGE="javascript"> <!-- window.onload = initialize('testMenu'); // --> </SCRIPT> Am I doing something wrong or is this not possible? Thanks for your help |
