JavaScript - Permanently Modify Javascript Code
I need educating please.
I have a javscript page (fred.js) that contains some variables and some code. I want to be able to change the variables (in particular an array) within fred.js on the server and store the new version of fred.js back on the server. I can write a php routine that stores the array in a MySQL table. Now I want to know how to write some code (and in what language) to read the MySQL table and update fred.js and store it back onto the Server. Can someone please tell me what language I should be using to do this (Ajax??) so that I can do some reading please. I could of course simply write some php code to read the table and pass the parameters to a js page and build the array as each person accesses the web page but this would be slow. Hence I would prefer to have the ability to update the js page and store it back onto the server. Similar TutorialsHi, I came across this thread and I've decided to use jmrker's code. Code: <html>
<head>
<title>Clock Example</title>
<script type="text/javascript">
function startTime() {
var d=(new Date);
var str = d.toLocaleTimeString().toLowerCase().replace(' ','');
var tmp = d.toLocaleDateString().split(' ');
var dm = d.getDate();
switch (dm) {
case 1: case 21: case 31: dm += 'st'; break;
case 2: case 22: dm += 'nd'; break;
case 3: case 23: dm += 'rd'; break;
default: dm += 'th'; break;
}
str += ' '+tmp[0].substr(0,3)+', '+tmp[1].substr(0,3)+' '+dm+', '+tmp[3];
startTime.out.innerHTML = str;
}
onload = function(){
startTime.out=document.getElementById("time");
setInterval(startTime, 1000);
};
</script>
<body>
<div id="time"></div>
</body>
</html>
However, I would like to modify some elements. Right now the date and time are displayed in this format: Quote: 9:58:45am Sat, Feb 26th, 2011 I would like to know how to change it to look like this: Quote: SAT 09:58:45 AM (for example) Could someone please break down the code and let me know what I need to change to get this to work? Or, if it's less trouble, just change the code for me? Thanks, I appreciate your time. Hi all.... newbie here. Have just finished my eccomerce site and it's ready to go but have come across a stumbling block. I use webplus4 which is a great web design program... except for one thing. The site search tool is very weak... it won't find results for words of less than 4 characters... and since my website is about plush pets this is important. For instance if you type in the breed 'pug' it says 0 results found. Same if you enter Old English Sheepdog, it ignores the entire search term because of the world 'old'. If you enter plush pug, it also ignores the entire search string. I don't have the money to purchase software nor the time and then configure the javascript to match my site. Is there anyone out there that can modify the following javascript file (jsSiteSearch.js) so that the search will not ignore words of 3 letters? Am aware that once modified I will have to replace the file each time but it will be worth it. By the way, no one on the webplus forums seems to know how to do it. Here is the code... (have removed all the keywords)... function GetSiteSearchResults(newWindow,frameObject,frameObjectName,fontFace,fontSize,fontColour,linkFace,lin kSize,linkColour,resultsText) { var sTerms=""; var iDepth = 0; var sURL = new String(document.location); if (sURL.indexOf("?") > 0) { var arrParams = sURL.split("?"); var arrURLParams = arrParams[1].split("&"); for (var i=0;i<arrURLParams.length;i++) { var sParam = arrURLParams[i].split("="); var sValue = unescape(sParam[1]); if( sParam[0] == frameObjectName) sTerms = sValue; if( sParam[0] == "depth") iDepth = parseInt(sValue); } } var d=frameObject.document; if (sTerms=="") {d.open(); d.write("<html><head></head><body style=\"background: transparent;\"></body></html>"); d.close();return;} var sBack=""; for (i=0; i<iDepth; i++) sBack+='..\\\\'; d.open(); d.write("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">"); d.write("<html lang=\"en\">"); d.write("<head>"); d.write("<meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\">"); d.write("</head>"); d.write("<body style=\"margin: 0px 0px 0px 0px; font-family: "+fontFace+"; font-size: "+fontSize+"; color: "+fontColour+"; background: transparent;\">"); d.write("<div id=\"wpSearchResults\"></div>"); d.write("<script type=\"text/javascript\">"); d.write("var wordMap = new Array(\"...........................................); d.write("function doNav(ind)"); d.write("{"); if (newWindow) d.write(" window.open(\""+sBack+"\"+linkMap[ind],\"_blank\");"); else d.write(" parent.window.location.href=linkMap[ind];"); d.write("}"); d.write("function wpDoSearch(searchTerms){"); d.write("var terms = searchTerms.split(\" \");"); d.write("if (terms==\"\") return;"); d.write("var results = \"\";"); d.write("var resultscount = 0;"); d.write("for (var i=0; i<wordMap.length; i++)"); d.write("{"); d.write(" var found=true;"); d.write(" for (var j=0; j<terms.length; j++)"); d.write(" if (wordMap[i].indexOf(terms[j].toLowerCase())==-1) found=false;"); d.write(" if (found)"); d.write(" {"); d.write(" results+=\"<a style=\\\"cursor: pointer; font-family: "+linkFace+"; font-size: "+linkSize+"; color: "+linkColour+"; \\\" onclick=\\\"doNav(\"+i+\");\\\"><u>\"+pageMap[i]+\"</u></a><br>\"+preMap[i]+\"...<br><br>\";"); d.write(" resultscount++;"); d.write(" }"); d.write("}"); d.write("document.getElementById(\"wpSearchResults\").innerHTML=resultscount+\" "+resultsText+" \"+searchTerms+\"<br><br>\"+results;"); d.write("}"); while(sTerms.indexOf("\"") != -1 ) { sTerms = sTerms.replace("\"",""); }; d.write("wpDoSearch(\""+sTerms+"\");"); d.write("</script>"); d.write("</body></html>"); d.close(); } Thanks so very much in advance. Any help asap will be much appreciated. Cheers Hi need help with a loan calculator script, i know the moderator frowns on such requests but i just have to, im willing 2 buy a cup of coffee if it works, i want the code below to display the total loan repayment amount instead of the monthly payment payment = principle * monthly interest/(1 - (1/(1+MonthlyInterest)*Months)) , eg if if l0an is 20$ payment is in 4 months, intrest rate is 15% display = amount to be repaid. thanks Code: <script language="JavaScript">
<!--
function showpay() {
if ((document.calc.loan.value == null || document.calc.loan.value.length == 0) ||
(document.calc.months.value == null || document.calc.months.value.length == 0)
||
(document.calc.rate.value == null || document.calc.rate.value.length == 0))
{ document.calc.pay.value = "Incomplete data";
}
else
{
var princ = document.calc.loan.value;
var term = document.calc.months.value;
var intr = document.calc.rate.value / 1200;
document.calc.pay.value = princ * intr / (1 - (Math.pow(1/(1 + intr), term)));
}
// payment = principle * monthly interest/(1 - (1/(1+MonthlyInterest)*Months))
}
// -->

I need help making it possible for the prefixes to be available when the post is being Modify? The user have to go back and change their prefixes to ended after they get the result for the outcome of the buy, sell, trade. When I hit Modify the prefix box was no longer available. It is on the subject line when I hit modify: Example. I have a thread title "Testing" and I chose Buy prefix when I started the thread. When I hit Modify, the prefix box is no longer available but the subject does say Buy:Testing. I would have to go and delete the Buy from the subject and manually type Ended. And also each prefixes a specific color if that's possible (i.e., Buy , Sell , Trade , Ended ) The prefix box now is below the subject line. I would love for it to be next to the subject line like in this forum.

Thanks, Alan Hey guys, wondering if anyone can help me. My JS knowledge is pretty non-existent. Basically I am currently using this code for a day countdown: Code: <script>
//change the text below to reflect your own,
var before=""
var current=""
var montharray=new Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec")
function countdown(yr,m,d){
var today=new Date()
var todayy=today.getYear()
if (todayy < 1000)
todayy+=1900
var todaym=today.getMonth()
var todayd=today.getDate()
var todaystring=montharray[todaym]+" "+todayd+", "+todayy
var futurestring=montharray[m-1]+" "+d+", "+yr
var difference=(Math.round((Date.parse(futurestring)-Date.parse(todaystring))/(24*60*60*1000))*1)
var dstring=difference.toString()
if (difference==0)
document.write(current)
else if (difference>0){
document.write("")
for (i=0;i<=dstring.length-1;i++)
document.write('<img src="/c'+dstring.charAt(i)+'.png">')
document.write('<img src="/days.png">'+before)
}
}
//enter the count down date using the format year/month/day
countdown(2011,08,17)

I like this script because it outputs in images. As you can see in my site at: http://www.bigbrothersite.co.uk/ (in the header) My question is, can that script above be adapted so it also works as a count up script. For example, from the 17th of august, can i somehow adapt it so i can use it to count up the days? Any help please. Thanks! I'm trying to create a form where the user enters data in a field and is redirected to a URL based on that entry - example: user enters 1234 and he is directed to mypage.com/1234/index.htm - if that folder does not exist it would give a 'try again' error. Any help would be greatly appreciated Thanks in advance Cyber-guys Edit: Problem solved.
I have a page that open two frames. Second frame, most of the page, is empty. First frame contains a form that retrieves user input, when you click the button, it send that input back to the original parent html, which detects the GET parameters, and builds a custom URL. I want to then load that custom URL in the 2nd empty frame. I figure I need to modify the src atttribute of the 2nd frame in the frameset, but I can't make it work. Code: <frameset id='parent' rows='10%,90%'>
<frame id='frm1' src='./form.html' />
<frame id='frm2' src='' />
</frameset>
<script>modFrmSrc();</script>
where modFrmSrc() checks for the GET values, builds the URL, and then tries to load the URL in frm2. Is there a way to get this done? Hello I've been in a hick-up trying to edit a JS code to perform a certain task, or literally speaking; sit there permanently on the webpage? now this is the code: Code: $("#nav_search a").click(function(){
$("#toggle_background").slideUp();
$("#toggle_search").slideToggle();
$("#main_search").focus();
return false;
and i would like to know if there's a way to permanently display the object instead of having the user to click>show? thanks in advance Greetings Programmers. I'm a graphics artist by trade but I also dabble in web design. I registered to this forum because I need your help. I've been handed a web project at work - to build an intranet site. My coding skills in HTML are sufficient to get the job done and I can plug in some JS and trobleshoot where needed but I've hit a wall with regard to one seemingly simple piece of code - I can't find a script anywhere that will generate a radio button that will, once selected, stay that way pretty much forever...or until I delete the listing on the page where these buttons will sit. I realize this isn't the concept behind these buttons but I need it to function this way because I'd like it to serve as a quick visual notification that a given employee review has been completed. These reviews will remain online for up to several months because there will be three reviews per employee over the course of that time. The selected buttons will indicate the reviews that are complete while the unselected ones will indicate which ones are still pending. I'd like the various levels of management viewing this information to know instantly, via the buttons, where we are with these reviews. So, that's my question, can a radio button be scripted to stay selected indefinitely once it's been clicked on? Thank you in advance for any help. It's greatly appreciated. - Sgt.

Each date represents an event. The code works well but I'd like to improve the declaration when several days with the same description are following to reduce declaration lines.

Thank you very much Gino I am using the simple password script from http://www.allwebco-templates.com/su...ect_simple.htm where the password is contained in the header script. I need to change the password, e.g. from Jan to Feb to Mar to Apr etc. How could I modify the script to contain the list of passwords, and have it automatically utilise/apply the correct password for the current month? To a non-javascript person like me this seems like it should be simple..... Can anyone please suggest a solution? Thanks muchly in advance. Is this possible? Code: String.prototype.trim = function(){
return this.replace(/^\s+|\s+$/g, "");
}
var myStr = " Hi what's up? ";
myStr.trim();
alert("{" + myStr + "}"); //will result in the original string, not the trimmed version
It's possible with numbers: Code: var myNum = 10; myNum++; alert(myNum); //11 |
