JavaScript - Encoding Issue
This issue is right at the cross point between the java and javascript. Basically, I want to DYNAMICALLY pass some Cyrillic characters (such as Алла Пугачева) at the runtime to the javascript function, as following:
Current text encoding setting is Cp1252 in JAVA IDE. response.getOutputStream().println("<script>test('" + testCoding +"');</script>"); If the testCoding is normal latin chracter (such as "abc, xyz"), this will work, so that at the runtime, it will execute the funciton test(param) and passing the parameter, "abc, xyz" to the javascript function test(param). The frontend javascript function test(param) will further display it as: field.innerHTML = param; But if it is the Cyrillic characters (such as Алла Пугачева), it won't work. The "Алла Пугачева" will be passed as the garbage character and displayed as so. How can I in the java class DYNAMICALLY set up the encoding so that the sysytem at the runtime will acccept the Cyrillic characters. I would believe I need to setup such ancoding as UTF-8. But I do not know how to? OR, How can I process the Cyrillic characters (such as Алла Пугачева), in the javascript function so that it can be displayed properly? Thanks Scott Similar TutorialsHi I am using Django to build my website i have some data on the server side which gets passed into my templates, this data become encoded using simplejson which is django python import my data structure looks something like this (but with a few more dictionary's thrown in " : Code:
archive = ({'id' :year.id, 'months' : allMonths})
encodedData=simplejson.dumps(archive)
The data is successful encoded and i pass the list into an external java script file, Now i need to figure out how to decode the data inside a JS function can anybody shed some light on this or even point my in the right direction. Thanks for reading Hello! I am trying to implement some JS that redirects a user after selection from a drop down box. The redirection includes a querystring so I want to use base64 to encode that. The 'goto' code below works fine if I remove the reference to the encode64 function. However when I use the encode64 function it doesn't work. So I'm guessing I have something wrong with the base64 portion. Code: <script language="JavaScript">
var keyStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";
function encode64(input) {
var output = new StringMaker();
var chr1, chr2, chr3;
var enc1, enc2, enc3, enc4;
var i = 0;
while (i < input.length) {
chr1 = input.charCodeAt(i++);
chr2 = input.charCodeAt(i++);
chr3 = input.charCodeAt(i++);
enc1 = chr1 >> 2;
enc2 = ((chr1 & 3) << 4) | (chr2 >> 4);
enc3 = ((chr2 & 15) << 2) | (chr3 >> 6);
enc4 = chr3 & 63;
if (isNaN(chr2)) {
enc3 = enc4 = 64;
} else if (isNaN(chr3)) {
enc4 = 64;
}
output.append(keyStr.charAt(enc1) + keyStr.charAt(enc2) + keyStr.charAt(enc3) + keyStr.charAt(enc4));
}
return output.toString();
}
function goto(form) {
var index=form.drpAccount.selectedIndex
if (form.drpAccount.options[index].value != "0") {
location="/billing-test.php?q=" + encode64(form.drpAccount.options[index].value);
}
}
</script>
hi, I would like your help on the following matter. I have a JavaScript file currently reading from another site xml file in (utf-8) and I would like to store those data in my database which is in SQL_Latin1_General_CP1_CI_AS. Is there any function in JavaScript that can encode (convert) text from utf-8 to SQL_Latin1_General_CP1_CI_AS or any other way to do that? Hi All, I need to know, how can we get character encoding in any site through coding. Actually i need to add an option in my website, in which i am entering a domain name(url of any website i.e. "http://www.yahoo.com") and through coding i have to find out the character encoding, doctype, frameset.. etc of the entered URL. OR Are there any such links which can help me out to get these parameters directly by passing the url only. Can anyone please help me out to get the parameters of any site....... waiting for ur reply`s Thanks gaurav joshi Hi, Sorry this is probably quite a noobish question, but I have a function which accepts the parameter "screen_name". I want to include this variable within some HTML, which is the code for a Twitter. Here is the function: PHP Code: var htmlTest = "<script src='http://widgets.twimg.com/j/2/widget.js'></script>" + "<script>" + "new TWTR.Widget({" + "version: 2," + "type: 'profile'," + "rpp: 8," + "interval: 6000," + "width: 250," + "height: 300," + "theme: {" + "shell: {" + "background: '#0e428f'," + "color: '#ffffff'" + "}," + "tweets: {" + "background: '#ffffff'," + "color: '#615161'," + "links: '#0748eb'" + "}" + "}," + "features: {" + "scrollbar: false," + "loop: false," + "live: false," + "hashtags: true," + "timestamp: true," + "avatars: false," + "behavior: 'all'" + "}" + "}).render().setUser('" + screen_name + "').start();" + "</script>"; var test = "hello"; document.getElementById('dynamic-content').innerHTML = htmlTest; } </script> The function works fine when I omit the HTML and just return "screen_name" to the target <div>, but it doesn't work as above. Can anyone spot what I'm doing wrong??? I have the following sample html file (attached). I am trying to display the calculated field using javascript and I created a function (I am a newbie) to do so. However, it persistently shows NaN instead of the required number. I have tried my best over a coupla hours racking my brains and the internet as to why it shows as not a number. I will appreciate any help. Thanks, Freaking IE. Must die. Really it must. Unfortunately, I have to code for it, and I can't figure out what went wrong he http://wyqued-design.com/dev/skyview/index.html The navigation, and layout, breaks in IE 7. Any ideas? -Emilie Quote: Hi, below code is only working in Firefox but not in Internet Explorer.

I had someone develop the javascript code to randomize the ads on my website: VillageOfManito dotcom and it worked great for many years. The ads were all contained in the left hand column which were called into the page via ASP code. Now I've been asked to split the ads into two columns, but when I divided the code and ads, the randomizer broke. See: VillageOfManito dotcom /template.asp You can also view the code for the columns he VillageOfManito dotcom /left_column.htm VillageOfManito dotcom /right_column.htm when I call up the individual columns (htm/javascript pages) by themselves, the randomizer works fine. the "break" occurs when the asp page is opened, where the 2 htm/javascript pages are called into the main page... are they causing conflict with each other? Hey everyone, I've got this slight problem with my code in javascript and I cant solve it to save my life and I don't really want to mess more things around incase it makes it worse. For some reason, when I click "get age" it just doesnt run, but the if statements seem to be running, any help would be appreciated Code:

hey guys im not quite sure how to explain this but i have a installed something called "hostpay" if any of you are familular with is, its on an client management system which has everything in it using ruby which was created by my provider. in it has a domain search and to use the domain search i use this code Code: <form method='get' action='http://www.nandahosting.co.uk/manage/dac' onsubmit="return check_domain_input()" accept-charset='utf-8'> <input type="text" name="domain" value="Domain Name Search..." onclick="this.value='';"/> <input name="search" type="submit" class="btn" value="" /> </form> but it will only work if you use that code inside the hostpay template files which was created by my provider. the hostpay is installed to a directory called "manage" What i am trying to do is to get a domain search box to work outside the hostpay folder(sent the information accross to the hostpay template, whatever is typed in the domain search box then search for the domain) i know this is possible as i have seen other people do it but not sure how to do it myself. for examlpe: www.pixelinternet.co.uk/domain-names.html (they have a domain box on that page which transferes it over, they have hostpay installed to a directory called "piXel") how do i alter the code i put on here to do what i want it to do? thankyou very much I am very new to coding, I am currently working on this design as my very first: http://img822.imageshack.us/img822/6533/unled1pd.jpg. I am currently working on the Image slider which is on the left side next to the login bar and headlines. I don't know where to start with this. If someone could walk me through or help me in anyway i would greatly appreciate it. Here is my current project LIVE: http://visionarycreativegrp.com/Demos/ForSale%20RED/# Alright,ill go straight to the problem. I want to get all the elements with a certain tag.However i can only get the first one. my code: Code: function getTags(tag) {
var x = document.getElementsByTagName(tag);
var y = x.length;
for(var i = 0; i <= y;i++) {
return x[i];
}
}
Hello, The code below assigns a value to the Latitude and to the Longitude table cells when the submit button is pressed. I would like to have these values appear in text boxes instead. Obviously I need to amend onclick="javascript:usePointFromPostcode(document.getElementById('postcode').value, placeMarkerAtPoint)" to make this work but I can't seem to. Assuming two text boxes with names lng and lat, how would I amend the line? Thanks Code: <p align="left">
<table bgcolor="#FFFFCC" width="300">
<tr>
<td width="100">
<b>Latitude</b></td>
<td id="lat">
</td>
</tr>
<tr>
<td width="100">
<b>Longitude</b></td>
<td id="lng">
</td>
</tr>
</table>

I'm trying to add an event handler for to my body, and for some reason which I can't figure out, it only works on Google Chrome. I wouldn't expect it to work in IE, but am wondering why it's not working in Firefox. Here's the relevant parts of the code: Javascript (in an external file) Code: var body = document.body;
body.addEventListener("load", Foo(), false);
function Foo(){
addEventListener(document.getElementsByName("start"),"click", alert("hello"), false);

It works great so far in Firefox, OK in IE and not at all in Chrome. There's only one problem I have with IE which is you have to click submit, you cant hit the enter key to search. Is this fixable? Ive tried writing a function where if it detects the enter key press, it "clicks" submit, but that didn't work. In chrome, I search for something but it says there's nothing to be found.
