Highlight All Found Words On An Htm Page From Input Box?

Aug 31, 2010

I have extremely text intensive web pages. A search engine can find the page but then my users have to search for the word using Ctrl+F. Google can highlight the found terms on the page but google does not index every page on my sites.

I need a way to highlight found words on my web pages by using an input box at the top of the page. The user will type in a word to find and the script will highlight all the found words on a page.

Here is code that is supposed to work to find an individual word but not all words. The code does not work for me.

In-Text Script Creation - Scan My Forum Page And Underline Words On That Page That Are Articles On The Wiki

Jun 23, 2011

I have a forum with over 5000 topics (lots of content in each topic) and I have a wiki-website with over 4000 articles. Both share the same database and are similar in context.

Now, I was wondering if there is a JavaScript out there that can could scan my forum page and underline words on that page that are articles on the wiki. For instance, if I have an article in the wiki entitled "Heart", where ever "Heart" appears in the forum, it is underlined and linked to that exact article on the wiki.

This conceptual idea is very similar to In-Text advertisements, such as Kontera, but I can't seem to find the scripting they use.

Itruncate All Words Greater Than 30 Characters When Page Loads?

Dec 23, 2010

How can I truncate all words greater than 30 characters using a class name when the page loads?Been trying to do this for about 5 hours. Trying to conside the following:

* Truncate long words and churn anything above the minimum length with an ellipse.

* Only truncate words and not the whole sentence or paragraph.

* Should truncate text that are inside HTML tags and not truncate the tags themselves.

* When you hover over the ellipse, it will show you the complete word.

* The long words are already truncated when the page load (SEO friendly).

* Block of text are included in a max of 25 <div> elements and a minimum of 1. That's why I'm not using ID.

So far I have this lines of code:

<script charset="utf-8" language="javascript" type="text/javascript">
function test(gaz) {
var sbText = gaz.innerHTML;[code]....

I got this from the web and modified it but not working as I intended it to be.

Highlight Text By Page User

Dec 11, 2010

I'm working on an educational website for reading strategies where I would like to have the possibilty for the user to highlight text and the possibilty to check their highlighted answers.User task: Mark all the cause and effect connectors (because, so, therefore etc) in the text.Now I want the user to take the mouse and go over the text and mark all these connectors in the text. After marking the entire text the user will get feedback for his correct and incorrect answers and a possibilty to correct his mistakes.If the user marks in the sentence "He got hurt, because he fell of his bike." the word 'because' I would like somewhere else on the page be written that he did this correctly. If he would mark the word 'hurt' I would like the user to get a feedback saying that this answer is incorrect.Is this possible with simple html or do I need something else. If I need something else what do I need and maybe there is already a ready to use script for this.

Gecko Find/Highlight Text In Page

Jul 9, 2002

People have complained that window.find() doesn't work, and everyone knows Gecko doesn't support IE's proprietary TextRange object, some have assumed you can't do this in Gecko.

On the contrary though:


Node.prototype.findTextMatches = [];

Node.prototype.findText = function(query, ignoreCase) {
this.findTextMatches.length = 0;
if (ignoreCase)
query = query.toLowerCase();

var tw = this.ownerDocument.createTreeWalker(this, NodeFilter.SHOW_TEXT, { acceptNode: function(node) {return NodeFilter['FILTER_' + (RegExp(query, (ignoreCase ? 'i' : '')).test(node.nodeValue) ? 'ACCEPT' : 'REJECT')] } }, true);
var offsets = [];
offsets[-1] = query.length * -1;
var totalMatches, trueOffsetDiff;
var range = this.ownerDocument.createRange();

while (tw.nextNode()) {
totalMatches = tw.currentNode.nodeValue.split(RegExp(query, (ignoreCase ? 'i' : ''))).length - 1;
for (var i = 0; i < totalMatches; i++) {
trueOffsetDiff = offsets[offsets.length - 1] + query.length;
offsets[offsets.length] = tw.currentNode.nodeValue.substr(trueOffsetDiff)[ignoreCase ? 'toLowerCase' : 'toString']().indexOf(query) + trueOffsetDiff;

range.selectNode(tw.currentNode);
range.setStart(tw.currentNode, offsets[offsets.length - 1]);
range.setEnd(tw.currentNode, range.startOffset + query.length);
this.findTextMatches[this.findTextMatches.length] = range.cloneRange();
}
offsets.length = 0;
}
return (tw.currentNode != this);
}

Node.prototype.highlightText = function() {
if (this.findTextMatches.length > 0) {
with (window.getSelection()) {
removeAllRanges();
addRange(this.findTextMatches.shift());
}
return true;
}
else
return false;
}


To search all text in the body, ignoring case, you'd go like:

document.body.findText('search query', true);

That loads up an array full of ranges selecting the text into document.body.findTextMatches.

To selectively highlight next occurences after executing findText:

document.body.highlightText();
// highlights first occurence

document.body.highlightText();
// removes previous selection, highlights second occurrence

// etc

Just calling that method over and over will successfully highlight instances. It returns true if it highlighted something, false otherwise,

Also, since I prototyped Node, it works not just in HTML documents, but can work in XML documents too.

Calling document.findText in an HTMLDocument may cause interesting results, as it searches through all the nodes, including <head>...

JQuery :: Highlight Content Based On Clicked Anchor From Another Page?

Sep 30, 2011

I recently had a request from a client and I'm not entirely sure this is possible. I'll try to explain it the best I can, as I can't share the development files yet...

We have a page with an image map of the United States. If anyone clicks on a state, it will bring them to a new

page. This new page contains a table that has named anchors on it, each row being a different state.

So, for example, if someone clicks on South Carolina on the map page, they will be brought here[code]...

The #sc anchor will scroll the new page down to the row in the table about South Carolina.

Is there any way to highlight the table row that the person is looking for? For example, if they click on South Carolina, they will be brought to this new page and the South Carolina row in the table would be highlighted.

Highlight Current "page" Without Page Refresh?

Jul 7, 2009

I'm using jQuery.LocalScroll to scroll a large page to the content depending on the link clicked. I have one css styled menu that stays in a consistent position while the rest of the page moves.It works well but as the page isn't 're-loading' for each section I can't think how I can indicate on the menu which section you are in.

Set The Priority To All And Not To The FIRST Found?

Jul 23, 2009

Venegal (Thx) wrote the majority of the following script and I must say , he did a great job:thumbsup:. there are a few extensions to script that are needed.

the priority within the searched user words and the found content on the site have been set to "the first found" will be hilited. e.g:

1. the wonderfull holidays
2. Sunny holidays
3. holidays in Spain

No.1 (div) only would be hilited if the user search words were e.g: "sunny holidays in Spain". I need the priority to be set so that all three divs would be hilited if the word "holidays" (for example) were searched for.

the Script:

function toggle(id, status){
document.getElementById(id).style.visibility = status;
}
function populateSearchField(){

Simple Search-type Page To Enable Users To Input A Model Number And Its Page Appears In A Inline Frame?

May 6, 2009

I am using a very simple search-type page to enable users to input a model number and its page appears in a inline frame. Its not a true search as it is simply relying on a person entering the correct html page name to find it. But this works perfectly in my application.The problem I have is that I cannot get the type box to accept enter key as a submitt, only a click of the mouse will submitt the request. If enter is pressed the box loses the users input but no action is taken.I think this may be a javascript issue. I have posted the code below.

gives?

window.onload = document.getElementById("thisThing").style.background =
"red";

Object And Method Can Not Be Found In IE?

Aug 4, 2011

Code:
var testi_box = {
spread: function(num) {
var main_obj=document.getElementById('testis');
$('.bg').stop().animate({opacity:1},800);
$(main_obj).stop().animate({height: 420}, 800);
var objs=main_obj.children;

[Code]...

So, I have this object that is set to fire its method the moment a user hovers their mouse over a particular div on my page. IT works just fine in all other browsers but IE7 or below. When i look at the error in IE it says that testi_box is undefined. But clearly it is defined. So, I'm lost. Is there something that I am missing?
