I'm using jQuery to pull a file asynchronously. I want to then sum the total of lines in that file that begin with "/". The file is a cache manifest and looks something like this...
Is there a simple approach to this? I've been messing with regex to get it done and not having much luck...
Does anyone know how I could (in javascript, or any client-side lang) cound the number of lines in a given textfile?
View 1 Replies View RelatedSay I have a <textarea> input and I want to strip all the blank lines (lines with only whitespace). I have this regular expression, why doesn't it do anything? I've tried different variations with the flags.The very same regex works fine in my text editor (Notepad2), and I can match all empty lines.And when I finally do get this to work, how would I remove the empty line?

I'm trying to make a small in page editor and was wondering if there is anyway to add line numbers to my textarea. Does anyone have a solution?
View 1 Replies View RelatedThere is a variable:
input = window.document.sidegenerate.input.value;
This variable points to a textarea of a form. Meaning that it has multiple lines.
What I want to do is have code added before and after each line. Example:
Original Input:
Line 1
Line 2
Line 3
Line 4
etc
This would be the output:
<h2>Line 1</h2>
<b>Line 2</b>
<b>Line 3</b>
<b>Line 4</b>
<b>etc</b>
As you can see, all the lines have had the same formatting added to them except for the first line. Which has different formatting.
Code:
function updatePreview(paramid, paramval, paramcomment)
{
[code]....
I wonder why I am not getting desired output.
expected output:
Actual output in IE8 is Amended Completed Matured
for(var i=0;i<document.all.elements.length;i++){
alert(document.forms[0].elements[i].id);
}
This code displays the ids of only controls in a form, but I'd like it to
display ALL items. For example, not just the ids of buttons, inputs, etc,
but any <span> elements as well. Is there something I could replace with
the "elements"? I tried tags but that doesn't work either.
All I'm trying to do is delete the lines which don't contain a particular
string. Actually a filter to edit a log file. I can find and replace a thing
with null, but can't figure out how to find the lines which do not contain
the thing.
Going further, I want to generalize and use a JavaScript variable containing
the decision string, but first I need to worry about the not-within-a-line
problem.
Can Jquery Detect How Many Lines of Text within a Div or A tag?
I am attempting to have different backgrounds depending on how many lines the left navigation takes up. For example if the item in the left nav only takes up one line it will have backgroundA. If the item in the left nav only takes up 2 lines it will have backgroundB etc.. Currently I have everything with backgroundA but there are a few that are taking up two lines or three lines and I can't shorten them as that is what the customer needs to have, but it looks horrible...
So can Jquery detect how many lines of text within a div or a tag and follow the css so it knows when it goes to another line and it can switch the background to something longer?

View 1 Replies View RelatedI have been using Javascript to write a web application for my company to use as a manufacturing control system. It is all working very well, but I have come across a basic problem that many of you may know the answer to.
I start my web page by referencing jquery and a couple of plugins. Then I add my own Javascript functions. Following that I add all the PHP code and functions, followed by the HTML. The problem I have noticed is that if I add another Java script function, something stops working. take the function out, delete not comment out. and all is well again. After pulling my hair out for a while, I realised that there seems to be a limit to the amount on lines of Javascript I can put into the page. The solution is simple, just gather all my Javascript code and put it in another file with a .js extension and add it as a reference in the top of the file after jquery. I can then add as many line of code as I like without a problem.
how the lines of Javascript are limited?
Explain what the first few lines in jQuery do?
That first line...what does that do in JavaScript? The anonymous function in parentheses...can't figure that out.
After that, the function is defined with the variables document, navigator, location, and jQuery. The last one being another anonymous function that has a local jQuery variable that points to yet another anonymous function?
Code:
I need to pass two lines of code through an onClick event.player1.sendEvent('STOP');player2.sendEvent('STOP');
I tried <a href="javascript:void(0)" onClick="player1.sendEvent('STOP'); player2.SendEvent('STOP');" title="<?php echo $list[$i]->title ?>">
only the event of player1.sendEvent('STOP'); is working... but not the second one. How do I manage this right here on the link rather than calling a fuction.
