Is there a tool that will monitor all the webpages I visit and it will save specific text/links/files?

the problem is that most of similar programs require you to enter a starting web address, then specify retrieval options and then let the program do the job I want an integrated solution to do this within my browser "as I browse"

I am interested in opera JS, (that has a functions on-DOM-load) or in firefox.

JQuery :: Use Document.write Statement To Write Html Tables On Client Side

Jul 27, 2010

I am totally new to jQuery and no good knowledge on javascript. However, I was assigned a task, to convert a javascript program to jQuery due to compatibility problem on browsers like Chrome and Safari. My program originally use javascript xmlDoc.load('....') to read XML file, and then use document.write statement to write html tables on client side. Something like this (the sample below may got lots of syntax problem as I jut want to show the major part):

document.write('<TABLE >');
var y=x[0].getElementsByTagName('NoOfRows');
for (i=0; i<=noofrows-1 && i<=y.length-1; i++){
document.write(' <TD>');

Now I changed to use jQuery, I can read the XML file elements. However, when I try to write the table, it failed:

Using Document.write To Write Current Date To Input Value.

Aug 5, 2002

Why doesn't this work? The input field doesn't show up at all. I know I'm just missing something really simple here.

<script type="text/javascript">
day = day.getDay()+1;
month = day.getMonth()+1;
year = day.getYear();
newdate= month + '/' + day + '/' + year;
document.write('<INPUT name=Date value='+ newdate + '>');

Making Document.write Write Into A Specific Location ?

Mar 24, 2011

I have a client that has ads on her website that really slow down the site. These ads are called by an off site javascript file and I want to use a jQuery(document).ready or similar method to call these files after all of the site content has loaded. But these files contain document.write functions to add more javascript files. Since I want to load the files after everything else has loaded, this in turn makes the page blank and then loads the ad. Is there a way to position where document.write will write to?

Using Document.write To Write A Variable

Mar 6, 2004

I'm pretty new to JavaScript and am having a problem. I thought what I am doing should work but it isn't.

Basically I have a form that people can put a quantity into. e.g. A, B, C.

I have a JavaScript function called comput that assigns values e.g. A = 5, B = 7, C = 9. Here is the start of the script:

<script language="JavaScript"><!--
function compute(form){
var A = form.A.value * 5;
var B = form.B.value * 7;
var C = form.C.value * 9;

I then declare a variable to add them up:

var ans = A+B+C;



This part of the script works fine. Now I want to write the ans variable. So I use:

document.write ("Your total is "+ans+"")
// --></script>

But it isn't working. Any ideas?

Document.write Inside A Document.write?

May 17, 2010

I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed.So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write.

Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script.Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script.

Write To A File.

Sep 26, 2007

I'm designing a an interface for my company and I need to be able to
interface with a text file. I chose Javascript for this because up
until this requirement surfaced, it's been the perfect tool.

How do I write to a text file using Javascript when you don't have
access to a server?

For reasons that I don't want to get into (political) I don't have
access to a web server so I can't do HTTP requests. It's all client-
side--ALL of it. Except for this issue, they love it.

Date And Write

Jul 20, 2005

1. The getYear() function returns 2004 in IE and 104 in Netscape. Is
that normal? It's no problem. I just add 1900 if it is less than 1000.
Maybe there is an updated function. Let me know.

2. Is there a way to use document.write after the page is displayed
without redrawing the entire page? I don't want to use a frame or
iframe. What I am trying to do is display a calendar and if the date is
changed then redraw it. Code:

Feb 12, 2009

This code writes a cookie to save the li's position after a user has sorted them to their preference. It's only designed to handle One unordered list. I'm trying to have it handle 3 unordered lists under the same page. It needs to write 3 cookies, and then read them when the user returns.

/// set the list selector
var setSelector = ".list1";

Write() And WriteIN()

Dec 11, 2005

I am new to this forum and have not had time to go over the questions already posted. I am also new to JavaScript, chapter 2 actually.

Is the write() and writeIn() method allowed in the one script section?? Here it is. I put in the <pre> but nothing happens.

<script type="text/javascript">

document.write("<p>The differentType variable is " + typeof(differentType) + "<br />");

differentType = "This is a text string.";
document.writeIn("The differentType variable is " + typeof(differentType) + "<br />");


The write() method always works but never the writeIn. Could someone please tell me what I am doing wrong?

Write To A Textbox

Apr 18, 2005

I've been asked to check if you can take the input in a form's textbox and on clicking the button, write to other textboxes on the form calculated values. I've failed miserably.

Is this actually possible, or do input boxes only take what the user enters or their default values? I can write the calculated values to other palces of course, if he just wants then displayed.

What To Use Instead Of Document.write

Jun 16, 2011

I understand that it is bad practice to use document.write inside a function as it can override other functions, so what would be better practice, writing to a <p> element, using document.writeln or are there others?

Document.write() Problem

Aug 25, 2005

I have a HTML document
displayed in an iframe. Controls on the HTML page are data bound to an
XML file. I use a drop-down list to move between the different
recordsets in the XML file and hence change the text displayed in the
HTML page.

I use JavaScript to display the contents of the iframe in a separate
window. The new window displays the HTML page. The problem is that
contents of the HTML page are always for the first recordset in the XML
file even when I change to a different recordset.

I found that if I omit the document.write from the code then it works
OK. Am I doing something wrong? Here's the JS code:

function displayFullScreen() {

newWindow ="", "newWin",
"toolbar=yes,location=no,scrollbars=no,resizeable=y es,width=screen.width,height=screen.height,left=0, top=0")

newWindow.document.write((getRframedoc()).document Element.outerHTML)
