JavaScript - Parse Html To Create Array From Specific Td Tags
Well after much trial and error I come asking for help. I am trying to write a greasemonkey script that scans a page for all the values between certain <td> tags. When I used firebug it shows what I am looking for as
<td class="username">THEUSERNAME</td> but when I view the source it just shows up as <td>THEUSERNAME</td> I want to create an array of the 100 <td>'s on the page that pertain to usernames but none of the other <td>'s I created a test page that mimicked the code, what I thought origionally, to be so I could test my script with ease. And it worked when there was an actually <td class="username"> This is what I have so far: Code: // ==UserScript==
//
//Displayable Name of your script
// @name EXAMPLE
//
// brief description
// @description EXAMPLE
//
//URI (preferably your own site, so browser can avert naming collisions
// @namespace http://something.com
//
// Your name, userscript userid link (optional)
// @author ME
//
//Version Number
// @version 1.0
//
// Urls process this user script on
// @include http://example.com
// ==/UserScript==
var test = document.getElementsByClassName('username');
alert(test.length);
test[5].style.color="yellow"; //Just to see if it actually worked
Similar TutorialsHow do I replace the string "rpg" only present in between <et> tags ? Code: <et>ReplaceOnlyrpg</et> After replacement it should look like this Code: <et>ReplaceOnly</et> Any advice is appreciated. Thank you From the these form fields I want to be able to create an array in Javascript containing the same 'codes' that feature between the option tags (not the value="X") Code: <select name="options-1" id="options-1"> <option value="">Select an option</option> <option value="1">KA-WH</option> <option value="2">KA-BK</option> <option value="3">KA-GN</option> </select> <select name="options-2" id="options-2"> <option value="">Select an option</option> <option value="4">BADGE-1</option> <option value="5">BADGE-2</option> <option value="6">BADGE-3</option> </select> <select name="options-3" id="options-3"> <option value="">Select an option</option> <option value="7">E-WH</option> <option value="8">E-GD</option> <option value="9">E-BK</option> </select> for example, from the above, I want a JS array for 'option-1' that contains KA-WH, KA-BK and KA-GN; plus an array for 'option-2' that contains BADGE-1, BADGE-2 and BADGE-3. The above form fields will be created dynamically, may contain more or fewer items. I then want to use the JS arrays to pull in images of which filenames match the 'code' in the array. I have a javascript that loads images on the page based on the date you select from a drop down menu. So the images are displayed dynamically, however they are numbered 1 through 20. Is there a way I can add a title tag to the images that will display on mouseover? Here's the page I am working on. I want to add title tags to the six images on the right side of the page. They change based on the date selected. webpage Thanks. Need help - sorry for the novice-ness of this. Have a computed field ("Subtotal").

I have this simple php array. The array will dynamically pull results from the db in the future. PHP Code: <?php $dataArray = array ( 'id1' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'GGP', 'timestamp' => date('m/d/y'), 'location' => 'Bellevue', 'comments' => 'It works!', ), 'id2' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Meijer', 'timestamp' => date('m/d/y'), 'location' => 'San diego', 'comments' => 'It works!', ), 'id3' => array ( 'icon' => '<img src="images/piicon.png">', 'app' => 'Point Inside', 'timestamp' => date('m/d/y'), 'location' => 'Boston', 'comments' => 'I guess its working? Maybe not exactly what we want yet though?!', ) ); echo json_encode($dataArray); ?> Currently if I have 100 results in my array, 100 results will be added to the table, 75 = 75 rows etc. What I am trying to plan out is a logical way to display one result from the array at a time. I am not looking for a chunk of jquery as an answer, better yet would be a plan/idea a programmer would you use to solve this. PHP Code: $(document).ready(function() { setInterval(function() { // get data $.ajax({ url: '/ajax/data.php', type: "GET", cache: false, error: function(data) { $("div#error").html('error: '+data); }, success: function(data) { var jsonObj = jQuery.parseJSON(data); jQuery.each(jsonObj, function(index, value) { var newRow = $("<tr><td>"+value.icon+"</td><td>"+value.app+"</td><td>"+value.timestamp+"</td><td>"+value.location+"</td><td>"+value.comments+"</td></tr>"); $("#mainTable tbody").prepend(newRow); }); } }); }, 5000); }); thanks 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. New to this, worked through the w3c tutorials and am really fascinated by some of the concepts. I'm only familiar with html, css, js (basics), so am trying to keep things as simple as I can for this. For simplicity I'll use books.xml with a listing of books. Each book has a <title><author><year><price> and <image> element. The images are stored in a folder called "images" a path is listed in the xml document. Using js and an array I can loop through the xml file and have it extract each node into a table, if I mouseOver a ROW in the table, it displays that listing in a DIV above and I would like it to display the image/thumbnail for that particular listing within another div called thumbnail which is in the same location regardless of which listing you mouseOver. Quote: if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","books.xml",false); xmlhttp.send(); xmlDoc=xmlhttp.responseXML; x=xmlDoc.getElementsByTagName("book"); i=0; function displayBook(i) { title=(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue); author=(x[i].getElementsByTagName("author")[0].childNodes[0].nodeValue); year=(x[i].getElementsByTagName("year")[0].childNodes[0].nodeValue); price=(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue); genre=(x[i].getElementsByTagName("genre")[0].childNodes[0].nodeValue); txt="Author: "+author+"<br />Title: "+title+ "<br />Year: "+year+"<br />Price: "+price + "<br />Category: " +genre; document.getElementById("showBook").innerHTML=txt; } Quote: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html> <head> <script type="text/javascript" src="myscript.js"></script> <link rel="stylesheet" type="text/css" href="stylin.css" /> </head> <body onload="displayBook(0)"> <div id="wrap" width="40%"> <div id="desc">Listing: </div> <div id='showBook'></div><br /> <div id="thumbnail">thumbnail <script type="text/javascript"> document.write(????????????????); </script></div> <script type="text/javascript"> document.write("<table border='1'; >"); document.write("<caption>Mouse over a cell to view description:</caption"); document.write("<tr><td class=top>Book Title</td><td class=top>Category</td><td class=top>Cost: </td></tr>"); for (var i=0;i<x.length;i++) { document.write("<tr onMouseOver='displayBook(" + i + ")'; >"); document.write("<td>"); document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue); document.write("</td><td>"); document.write(x[i].getElementsByTagName("genre")[0].childNodes[0].nodeValue); document.write("</td><td>" + "$"); document.write(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue ); document.write("</td><td>"); document.write(x[i].getElementsByTagName("image")[0].childNodes[0].nodeValue ); document.write("</td></tr>"); } document.write("</table>"); </script></div></div> </body> </html> So the way this looks is there's a grey div. At the top it says listing, and when the body loads it lists the [0] first entry from the array. To the right of this is a small div called thumbnail that is empty and I would like it to load the relevant image from the path in the <image> tag in the xml file. Below the listing is a table with 4 columns (title, genre, price, image) and an equal number of rows to the number of listings in the xml file. Under the "image" column it just shows the path to the image. So how do I tie the empty thumbnail div to the listing so it'll just add the path from the xml <image> tag into a <img src="pathnamefromxmldocument"> Thanks in advance! Basically what I need to do is cause a bit of HTML to only display on a specific page. I have figured out how to do most of the work i.e. figuring out what page that the code is being displayed on, etc. However, for some reason the DOM element that I am using will not update based on the Javascript. I have searched the Internet for a solution and unfortunately I have found none. Here is the version of the code that I am currently working on: Code: <html>
<head>
<script type="text/javascript">
window.onload = function DisplayButton() {
var DesiredPage = 'Page to Display';
//Page that I want the code to display on
var sPath = window.location.pathname;
var sPage = sPath.substring(sPath.lastIndexOf('/') + 1);
//This determines and places in a variable what page that the code will be on
if (sPage == DesiredPage) {
document.getElementById('HiddenCode').style.display = "block";
}
}
</script>
<p Id="HiddenCode" style="display:none">Code only to be displayed on indicated page</p>
</head>
</html>

Hi, I have a text area that I want to add simple html formatting buttons to. The user should be able to: - highlight text and click a 'bold' button - highlight text and click 'itallic' button - Add bulleted list - Link I've looked at a number of WYSIWYG javascript examples, but they seem to accept Microsoft Word formatting, which I dont want. Hi, I wanna make a form that receives: textbox URL And textbox Anchor and result will be two anchors one <a href, and one phpBB Example: Url: www.pushpin.co.il Anchor: pushpin Results: <a href="http://www.pushpin.co.il">pushpin</a> [ url = http://www.pushpin.co.il/ ] pushpin[ /url ] Help? I came across some embedded JavaScript code and I noticed some weird “HTML comment-like tags” within embedded JavaScript that are getting rendered in FireFox but not IE. Specifically the closing tag "//-->" And the JavaScript code between these tags is functional (not commented out)! Code: <SCRIPT type=text/javascript> <!-- .... //--> </SCRIPT> What are these? Example usage: Code: <SCRIPT type=text/javascript>
<!--
var zz, zv, d, fTSR;
d = new Date();
fTSR=0;
zv = d.getTime();
zz = "&zz="+zv;
var gBF=false;
function GoTo(u){window.top.location = u + zz;}
function Go(u){window.top.location = u;}
....
//-->
</SCRIPT>
I was looking at that old Strawberry Fields problem and I thought I'd see about solving it in JavaScript. What I want is an array of chars so that I can set individual elements in the array of arrays. Strings are apparently immutable and can't directly be changed? Here's my code. Code: var field = new Array();
var string0 = "..@@@@@..............."
var string1 = "..@@@@@@........@@@..."
var string2 = ".....@@@@@......@@@..."
var string3 = ".......@@@@@@@@@@@@..."
var string4 = ".........@@@@@........"
var string5 = ".........@@@@@........"
for (var i = 0; i < 6; i++) {
field[i] = new Array();
field[i] = eval("string" + i + ".slice('')");
}
document.write("field's type is " + typeof field + "<br>"); // object? but it should be explicit array
document.write(typeof field[1]) // string? it should explicitly be an array, then it was filled with array elements
document.write(typeof field[1][2]); // string - ok, I understand this bit
document.write(field[1].length);
document.write("<br>");
for (var i = 0; i < field.length; i++) {
field[i] = new Array();
for (var k = 0; k < eval("string" + i + ".length"); k++) {
field[i][k] = eval("string" + i + ".charAt(" + k + ")");
}
document.write("<br>");
}
document.write("field's type is " + typeof field + "<br>"); // seriously, an object?
document.write(typeof field[1]) // why is this an object instead of an array?
document.write(typeof field[1][2]); // string, yeah, I understand this as well
document.write(field[1].length);
document.write("<br>");
Also, it looks like I can't overwrite a 1-length string that's in the array of arrays. For instance: Code: newField = field; //for loops newField[i][k] = 0; // does nothing, newField's elements remain the same. Hi, I am a begginer in javascript, please help on below I want to create an object with nested objects array like following: var country{ var states=new array(); } var state { city,pincode } this should be called like var city= country[0].state[0].city; any idea will be appreciated Hi! I'm very new to Javascript so first I want to apologize for my lack of knowledge, what I'm asking is probably really simple to do. Im have a folder full of images. Each image is named with an incrementing number like vidseq000001, vidseq000002, vidseq000003 and so on. I'm trying to use a jQuery plugin called "reel" to make the sequence animate. For that it seems I need to put the images inside an array. I know how to manually enter each image inside the array like var [ vidseq000001, vidseq000002, vidseq000003, ] But this becomes quite tedious with over thousand images. What would be a smarter way to put all my images inside an array? Dear All, Here I am facing one issue, that I want to removing all html tags except BOLD,ITALIC,UNDERLINE & UL,LI. Means if my data is like, <b><i> Test Data </b></i> <input type="text" name="test"> <script> function test() { ............. } </script> Then I want the following output.... <b><i> Test Data </b></i> function test() { ............. } Means I need the data with tags BOLD,ITALIC,UNDERLINE & UL,LI not any else tags..... I have tried with this strInputCode.replace(/<[^>]+>/ig,""); but its removing all html tas that i dont want |
