JavaScript - Replacing Html Lines Using Javascript
Hi. I have the following line in my HTML file <table class="bz_buglist" cellspacing="0" cellpadding="4" width="100%">
And I need to use javascript to change this line to <table id="main_table" class="bz_buglist" cellspacing="0" cellpadding="4" width="100%"> . I just need to add the ID part. How can I do this? Is there a method of replacing the line, or a way to "add attribute"? thanks! kev. Similar TutorialsI have the following code that works fine: Code 1 Code: <script type="text/javascript">
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
</script>
I also have the following code that works fine: Code 2 Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
MyWindow=window.open('http://www.site.com','MyWindow','toolbar=yes,location=yes,directories=no,status=yes,menubar=yes,scrollbars=yes,resizable=yes,width=640,height=480,left=1,top=1');
}
}
However, I want to replace the blue code in the Code 2 immediately above that opens the window with the red code in the Code 1 section that opens the GreyBox window. I tried the following but it's just not working: Code: function DoTheCookieStuff()
{
visited=getCookie('visited');
if (visited==null)
{
setCookie('visited','yes',365)
AJS.AEV(window, 'load', function() {
GB_show("Special Presentation", "http://www.site.net/temp/images/ads/special.jpg", 352, 600);
});
}
}
Thank you. I'm a bit of a Javascript noob, so please bear with me! I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML. The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills! For example, in the following code I'd want to replace all instances of <li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li> Code: <div id="downloads">
<p>Please click on your downloads below:</p>
<ul>
<li><a href="index.pdf">Index</a></li>
<li><a href="chapter1.pdf">Chapter 1</a></li>
<li><a href="chapter2.pdf">Chapter 2</a></li>
<li><a href="chapter3.pdf">Chapter 3</a></li>
<li><a href="credits.pdf">Credits</a></li>
</ul>
</div>
The Javascript I have so far is: Code: <script type="text/javascript">
var aEls = document.getElementsByTagName('a');
for (var i = 0, aEl; aEl = aEls[i]; i++) {
aEl.href = aEl.href.replace('index.pdf','contents.pdf');
}
Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this! Any pointers would be much appriciated. Here I have a code to redirect a page to one of these three pages. But is there a limit to the amount of websites I can add? Code: <script type="text/javascript"> var urls = new Array(); urls[0] = "http://www.google.com"; urls[1] = "http://www.youtube.com"; urls[2] = "http://www.codingforums.com"; var random = Math.floor(Math.random()*urls.length); window.location = urls[random]; </script> Would I be allowed to have, say, hundreds of thousands of different sites? Or would the script stop working? Thanks. Hi, Does anyone know how to make a javascript regex ignore new lines? I have this Code: html = html.replace(/<!--(.*?)-->/gi, ''); // HTML comments which matches single line comments like - Code: <!-- this is a comment --> but not this - Code: <!-- This is a comment on multiple lines --> I think the answer lies with [\s\S] but I can't get it to work e.g. - Code: html = html.replace(/<!--(.*[\s\S]?)-->/gi, ''); // HTML comments Any help will be greatly appreciated Cheers Al favorite I'd like to modify a form on www.formsite.com (form builder app): username: testuser password: password I would like to use the nicedit.com's inline content editor's js to transform my textarea's into a richtext area. At present the nicedit editor works well in creating the richtextarea. However, the KEY point is that I would like formsite's form to pipe in the the created html and render it with the html component of formsite. Currently, the pipe function in formsite will only put out the html syntax in it's html module. action seen he http://fs8.formsite.com/testform/form1/index.html So this would be: 1. checking out my form on formsite.com 2. the script from nicedit.com is already installed in an html component. 3. changing or telling me the scripts/tags/or whatever for formsite form using formsites form builder (which allows some html/script editing). 4. changed so as to render the rich text entered on page 1 in page 2 instead of the html syntax. Any other solutions using formsite and any other richtextarea solutions would be great too! Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled! I create the following code but it did not work <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> <script language="JavaScript" type=""> function changeColor(){ document.bgColor = "Gray"; } </script> </head> <body> <script language="JavaScript" type="text/javascript"> var person = ""; person = prompt('What is Your Name:'); if (person == "Foo") { document.write("<h1 />Welcome " + person); document.bgColor = "Yellow"; } else { document.write("<h1 />Access Denied!!!!"); document.bgColor = "Red"; document.getElementById("gree").disabled = true; } </script> <div> <p/><input id="gree" type="button" value="Gray " onClick="changeColor();"> </div> </body> </html> as you can see I used the: document.getElementById("gree").disabled = true; but it did not work , could you please give an idea how I can solve this problem? Thanks hi, I am curious about the use of appendChild() here... I have a solution that does what I want it to do, like this: Code: var sidebarEntry = createSidebarEntry(poly, html); sidebar.appendChild(sidebarEntry); sidebar.replaceChild((sidebarEntry),sidebar.firstChild); but it seems to be going the long way around. Not that it matters much (I guess), but all I want to do is to add an item to the sidebar and when a new item is added, remove the existing one. I tried just using relaceChild() on its own, but the code seems to need something to be replace... Is the above the best way to do it? Or is it possible to set the child to some dummy position like null to begin with, so that the code is not constantly reloading and replacing items (which is what I understand is going on now)? here's the page I'm working on, if you want to see the rest of the code. I appreciate any thoughts. Is it possible, when a page is reloaded, to replace a link to a javascript in the head with a link to a different script?
Hey guys... Basically I need a function that will remove numerous elements from a page based on their class. I then also need a function to bring those elements back afterwards. If anyone is wondering, I'm trying to add buttons to remove/add images. Thanks! Hi, I am quite new to JS and is currently building a website with a little of JS Function. Ok, so I have a Page tat consists of 10 images. Each images when on mouse over, will display a larger version on the images, using JS(onmouseover). Then, I will have a next button that will replace all the images, using Ajax, which means my page will not be reloaded. The problem comes here when I have to replace all the onmouseover effect. I can replace all the thumbnails without problem, but the onmouseover I have problem replacing. Is there anyway that I can dynamically replace all the onmouseover? Any help will be appreciated. Thanks Hi, I know how to replace all the + signs in a url string by spaces, like this: newstring=oldstring.replace(/[+]/g," "); but how do I replace a substring by a comma easily? This doesn't do it: newstring=oldstring.replace(/[&menuitems]/,","); Thanks in advance for any help. I'm sorry this is simple, but: Code: function printInput(f){
var ifr = window.frames['printFrame'];
var v1=readCookie('lesson');
if (v1==1){v2='WORKNOTEPAD1'}
if (v1==2){v2='WORKNOTEPAD2'}
if (ifr){
ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
ifr.focus();
ifr.print();
}
else { something }
}
In this line: Code: ifr.document.getElementById('content').innerHTML=f. v2 .value.replace(/\n/g,'<br />');
How can I make it stop erroring and act as if the "v2" were, say, "WORKNOTEPAD2"? If the line contains the string it all works fine. It must be so simple... Hey folks. I currently have a PTZ camera that is taking screenshots every minute (or so) and sending a copy of that image (overwriting the previous one) to my website. Basically, the visitors to the website will be greeted with a live screenshot. The problem is if the visitor hits the website at just the right time, the screenshot won't be loaded completely while the 2nd most screenshot is being overwritten... creating an empty image load (the dreaded red X). What I am looking to do with Javascript is to be able to load a generic image in the scenario in which no image loads. Is that possible? I tried doing something like the following and onload-ing it, but it wouldn't work. Any help would be appreciated. Thanks! Code: <script type="text/javascript">
<!--
function replaceSrc() {
var images = document.getElementsByTagName('img');
for(var i = 0; i < images.length; i++) {
var img = images[i];
if(img.src.length == 0) {
img.src = 'images/garbage.gif';
}
}
}
-->

I have 16 links on a page, when each link is clicked, I need to change text that is on the page. This is Page 1 link 1 This Is Page 1 link 2 This is Page 2 ... link 16 This is Page 16 How can I do this? Excuse my ignorance, this is my first JS project Ok, i have a javascript that creates a table then appends it to an empty div. This works fine in FF, however it fails to work in IE8. [edit] I have decided to post the entire code since I wasn't having any luck getting any suggestions. Maybe now someone can help me out. Code: function createTable() {
var machine = document.Catalog.machine.value;
var dSearch = document.Catalog.dSearch.value;
var section = document.Catalog.section.value;
var x = xmlDoc.getElementsByTagName('record');
var y = xmlDoc.getElementsByTagName('data');
var newEl = document.createElement('TABLE');
newEl.className = 'resultsTab';
var tmp = document.createElement('TBODY');
newEl.appendChild(tmp);
var row = document.createElement('TR');
var n = 1;
var headings = new Array("Col1", "Col2", "Col3", "Col4", "Col5");
var dcount = 0;
//for (t=0;t<10;t++) {
for (t=0;t<y[0].childNodes.length;t++) {
if (y[0].childNodes[t].tagName == "record") { // it is required for FF to work properly
dcount++;
}
}
if (document.Catalog.thumbImg[0].checked) {
var container = document.createElement('TH');
var theData = document.createTextNode("Pic");
container.className = "topline1";
container.appendChild(theData);
row.appendChild(container);
}
for (h=0;h<headings.length;h++) {
var container = document.createElement('TH');
var theData = document.createTextNode(headings[h]);
container.className = 'topline' + n;
container.appendChild(theData);
row.appendChild(container);
n++;
}
tmp.appendChild(row);
switch (searchtype) {
case 1:
var objRegex = new RegExp(machine);
break;
case 2:
var objRegex = new RegExp(section, "i");
break;
case 3:
var objRegex = new RegExp(dSearch, "i");
break;
default:
document.getElementById("replaceTxt").innerHTML = "<p>There was an error processing your request.</p>";
}
var rowColor = 1;
var noResult = "false";
for (i=0;i<dcount;i++) {
var row = document.createElement('TR');
var searcharr = new Array();
for (j=0;j<x[i].childNodes.length;j++) {
if (x[i].childNodes[j].nodeType != 1) continue;
searcharr.push(x[i].childNodes[j].firstChild.nodeValue);
}
var searchstrg = searcharr.toString();
if (searchstrg.match(objRegex)) {
var t;
var m=1;
if (document.Catalog.thumbImg[0].checked) {
var pn = "images/"+searcharr[2]+".jpg";
var container = document.createElement('TD');
var refLink = document.createElement("A");
refLink.setAttribute('href', "javascript:viewImg(\""+pn+"\")");
var imgHolder = document.createElement("IMG");
imgHolder.setAttribute("src", pn);
imgHolder.style.height = "75px";
refLink.appendChild(imgHolder);
container.appendChild(refLink);
container.className = "img"+rowColor;
row.appendChild(container);
}
for (t=0; t<searcharr.length; t++) {
container = document.createElement('TD');
var theData = document.createTextNode(searcharr[t]);
container.appendChild(theData);
container.className = 'line' + rowColor + '_' + m;
row.appendChild(container);
m++;
}
tmp.appendChild(row);
rowColor == 1 ? rowColor++ : rowColor--;
document.getElementById("replaceTxt").innerHTML = "";
document.getElementById("replaceTxt").appendChild(newEl);
noResult = "true";
}
}
if (noResult=="false") {
document.getElementById("replaceTxt").innerHTML = "<h3>Sorry, there was no match to your search. Please try again</h3>";
}
}
xmlDoc is the xml object from my import xml function. it is working correctly. IE does not give any JS errors, it just does nothing. If I put text in the Code: document.getElementById("replaceTxt").innerHTML
field, IE displays the text in the correct spot so I know the code is working. I also verified the data is being written correctly to "newEl" via IE 8 debugger. IE just does not want to append the newEl child to the <div> tag. This is where I assume the problem is. Hi Guys/Gals I am trying to do a small website for our family to keep track of each other's home address and etc.. using asp for the codes .. (its been ages since i indulge myself) i have 2 forms in which in FormA, i will key in the following address 666, ST Avenue #03-09 Anchor View Residence 123456 when i click on submit it shows this on FormB 666, ST Avenue #03-09 Anchor View Residence 123456 my question is how do i get it to be shown as 666, ST Avenue #03-09 Anchor View Residence 123456 in FormB in my formB.asp, for the particular code, all i wrote was Code: {Form.address}
I am in need of advise, have been stuck here for the past 1 day, not knwing wat to start or how to start. Thank you Code: var bakaBanner;
bakaBanner = document.getElementById('head');
if (bakaBanner) {
var str=/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/;
document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png"));
}
Alright, here's the deal... This is a script to be used in Greasemonkey. The page this is for changes their banner every 5 minutes, the name changes and it could be either jpg or png. I'm fairly certain my regex itself: \/images\/banners\/[A-Za-z0-9_]+.[a-z]+ Is correct... Here's an example of what it's looking through: Code: <div id="head" style="background-image: url(/images/banners/kiminitodoke.jpg);" > <div id="header_left"> <div id="rss"> My guess is that it has something to do with this line: document.write(str.replace(/\/images\/banners\/[A-Za-z0-9_]+.[a-z]+/, "http://img218.imageshack.us/img218/5904/revyblacklagoon1.png")); I'm new with Javascript, so I don't really understand why it's not working... :/ Hello every body i have a problem with javascript i wrote a script which process the entry of a text area 1 and i made the script process only the first line of the entry i want a method to make the script to process all of the lines which the user enter it OR make a varibals to every line entered from the user i am so sorry about the weak language thank you in advance i have a program which gets values from different arrays and displays them on screen. how do i insert a break every 5 lines so its easier to read?
