JavaScript - Encoding From Utf-8 To Sql Latin1 General Cp1 Ci As
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? Similar TutorialsHi, To put it bluntly I am a newbie to Javascript. I manage my own site using skills I have developed through learning code and need some help with debugging. My website is www.simplysafes.co.uk, in my IE it tells me I have an error with line 106 and char 2. Can anyone help me with this?? I would really appreciate it. Thanks in advance. James Hi, I need help creating a function. It want it to: run when the page loads and every x seconds after. On loading I need it to connect to a db(preferably w ajax) and store results as variables I can reuse in other functions. And finally, after some math equations I can do, print the results on the page. I've been toying with this and I've realized its not as easy as I thought. Think I'm having problems with variable scope. Php is my main scripting language, of which I am fluent and have a working version of this. But I want it to run on the client side and relieve my server. Sorry if this is vague or incorrectly formatted, I'm on a phone browser. A guide or detailed demonstrations would be great, however pointing me in the right direction would me most apreciated. Hello; I'll begin like so many others before me, and apologize now if this post is in the wrong place, but since I don't exactly know what type of code I need, I'm not sure where to post this query. Let me preface this request by stating the obvious; I have almost no knowledge of coding. I've been watching tutorials for help with building a site for my small service-type business. I need coding that will allow my visitors to input their zip code to see if they reside in my service area. After they enter the zip and click the submit button, a page should pop up with one of two messages when they either are or are not in my service area. (I would undoubtedly need to list [somewhere in the coding] all the zip codes that are within my service area, and any zip codes not listed would bring up a message that the visitor is outside my service area.) I hope this makes sense, and someone can point me in the right direction. Thank you, in advance to any and all who respond, and keep in mind that you may have to dumb-down your responses for me to be able to understand. I've only just stated to teaching myself the general basics of web development, and I've hit a problem which I haven't been able to fix, even after some extensive research I haven't found a solution. The problem is not in the HTML I'm quite sure, hence why I deemed this to be the best place to post this. I'm sorry for wasting your time on something stupid like this, but I'm completely lost! Extra: I really couldn't think of a title that could describe this 'problem', my bad. Description: When clicking the calculate button nothing happens, but when I changed the code inthere to something easy (just print a line in a HTML paragraph) it worked. So by that I was able to deduce the problem lies somewhere in the Javascript. Code: <!DOCTYPE html>

NOTE: I have not tested the logic of your code to see if it give the right answers, but this should get you started by at least seeing some results displayed. Primary problem was not using Math. before the math commands like pow and sqrt. Also, need quotes around id values in the document.getElementById statements And those statements require a value associated with the element Plus, it returns a string, hence the need for a Number() function or some other string to conversion. It is always a good idea to check the error console on most browsers to get an idea of the simple problems. That's where I found most of your errors. Code: <!DOCTYPE html>

Good Luck! I create a cookie on my homepage that tracks a number, the next time they view, js calculates another number and subtracts the saved number. Is the cookie value created accessible from a page other than the home page? i.E. I want to create a popup window that shows the calculation but i can seem to pass the variable generated from my external js script to the internal script/page. Am i able to call the getCookie class i created from the internal script even if the class is held in the external script or is it only accessible from the page that created the cookie? If its a dumb question, sorry im relatively new. I have a general javascript question. It may apply in this forum but maybe in the asp forum. I have a java applet on a site that I am building. If someone visiting the site doesn't have their javascript turned on, and chooses not to, is there some line of code that I can use that will detect that and replace the applet for an image I create? The site is developed in asp, but being that it is a javascript question, I thought it may apply here. Gary Hi could someone please help?... I am a total beginner to javascript... but does anyone know of a code, including links to an image folder, for displaying 6 fullscreen images in random order without repeat for a given user? I've seen specific examples using shuffle on the site, but could anyone write a general code for any given images? Many thanks in advance Hi, as the title states, I'm trying to learn some basic javascript, more particularly, jQuery. I HATE having to "allow" active content to run on my IE browser. Is there a way to allow active content permanantly? Instead of having to click allow each time I refresh or reload my test pages? Also, IE keeps freezing or crashing when I run pages with scripts on them. Is this just my browser? or something to do with the active content permissions? Trying to google my questions, but no luck yet. Hello, I'm new to this forum. I want to improve my ability to write JavaScript and am looking for a friendly place to find some constructive criticism and suggestions on my code. This script does not have any practical use (that I can think of); it calculates prime numbers. It is just an exercise. I am looking for suggestions on all aspects from the CSS/aesthetics to the HTML and of course the JavaScript. I posted the script here. One definite thing that bugs me is the cursor is not in the text field when the page loads. Also it would be better if the user had the option of hitting the return key in addition to the submit button. Suggestions appreciated. Code: <!DOCTYPE html>

Hi 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 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 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 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??? |
