I have the following piece of code in use on a vBulletin forum:
function sel(postid,username)
{
if (document.getSelection) {
var str = document.getSelection();
[Code].....
What this does is if the user highlights some text in a post and presses a button, it inserts the highlighted text into QUOTE tags within the Quick prely box.
This works fine...however, it doesn't check if the user has actually selected some text. Many users simply press the button thinking it will quote the entire post, when in fact it will simply insert some "blank" quote tags.
What would I need to add into this to check that some text has been selected, and return an alert if not?
i want to know is there any inbuild function to add spaces in javascript after particular interval..!!? there is string '00009999' i want to add blank space 0000 9999 after every 4 digits.?
I want to check a string if it contains certain letters.the string is Elephant and if i check it for the letter "e" i want it to display all the "e" letters.If i use the following code it always just displays the first "e". but i want to display all the "e".
Using jQuery v1.4.2, Firefox 3.6.6, Chrome 4.1, IE 6,7,8.
I'm using jQuery .css() function to get the value of the css attribute "background". The attribute has not previously been assigned a value (either in script or style sheet).
e.g. alert($(this).css("background"));
In Firefox and Chrome, the return value is an empty string (""). However in IE 6,7,8, the return value is "undefined".
Because css() in IE doesn't return a blank string, doing indexOf() raises an error.
cross-browser scripting compatibility, for jQuery to return a blank string *for all browsers* if the css attribute isn't set. Otherwise we have to check for both "" or "undefined" which is the sort of pain jQuery users are trying to avoid.
I have a frame_structure.html divided into column-frames(frame_menu.html and frame_content.html). When user click on menu links, I want the statusbar not to display the link.
I know how to do inline onMouseOver (... true;"...); with each href in frame_menu.html. But I want to write just one time using <script>. I've tried in frame_menu.html
There must be an apostrophe or some other little javascript nuisance that I'm still including in this script, but whenever I try it out, nothing shows..it is supposed to randomly display some text and a link Code:
The following code is my form, if one of the fields is left blank (and there will usually be one left blank) the calculation returns NaN and will not perform the task needed. I initially had the form set to calculate in metric kilometers and liters, when I converted the math portion to miles and gallons it started doing this.This is the line giving me the problems:
var cars_emissions=(((mileage1/efficiency1)*0.3732417216/1000)+((mileage2/efficiency2)*0.3732417216/1000)+((mileage3/efficiency3)*0.3732417216/1000)); The original was:
I know I can use the functions like parseFromString() to access and modify an existing XML documents, but is it possible to use JavaScript to create a blank xml document?
I want to take data entered into the client, package it up as XML and use ajax to transmit it to the server. So far I've written my own class to create a simple xml document, but I'd like to do it properly with the inbuilt functions.
I have a three field contact form on an HTML5 page. Using CSS3/HTML5 techniques, the fields change state as the info is entered properly (green OK symbol if good, red "!" if not, etc). That all works as expected in all browsers.
My final hurdle is preventing the form being submitted with nothing entered in the fields. I have done hours of research and have tried several ways of writing the checkFeedbackForm function. My problem is that none of the solutions I've found are recognized by FireFox (mac and pc) and IE. They just ignore the javascript and allow the empty form to be emailed.
I'm building my portfolio website. I'm an illustrator and graphic designer (for printing). My website uses html and css. I introduce a jquery plugin to create a slide show with my work. Until then, everything was working well. The problem appears when I introduce php to my code in order not to repeat the navigation bar all the time. With php and the jquery together I get a blank page in my browser.
This link shows the blank page I'm getting using php and jquery together. [URL]
This is an example of the site without the jquery. [URL]
Could someone please help me with this thanks.

I'm using an swf on a page that contains javascript function calls that relate to an external js file linked to the swf's parent html document.
Still with me? Ok.
The idea is that when javascript is enabled all the extras work, and when it is not enabled, they don't (though the page still displays the initial content).
This behaves as intended in Camino with javascript both on and off. This also works fine in IE5Mac when javascript is on.
Problem is, when javascript is off in IE5Mac, the first instance of javascript in the swf causes the entire browser window to go blank (no html content, no back button, no reload. Nada).
I've tried conditionalising the function ( if (document.geElementById) ) both in the function declaration itself and the function calls within the swf, but the problem still occurs. Fwiw, the function calls within the swf relate to a function that alters html text using the innerHTML branch of the DOM.
Is this a documented bug with IE5 (Mac?) or is there some way round this that simply gets IE5Mac to ignore the function calls coming from the swf when javascript is disabled? Alternatively, is there some way of getting the swf itself to ignore any javascripts contained insied if the browser is not javascript-enabled?
I would like to have a blank space to separate the options in the "Select Color/Size drop down box" I would also like to have an alert('Please select a size'); show up if someone chooses the blank space. I have tried to do this but my attempts have been fruitless so far. Code:
First time back here in a while, but I'm trying to get proficient in JS. I want to make my input element reset its value attribute to blank, which is originally set to "your e-mail". You know the effect you see on forms that have text in them, then with the onclick attribute, you can clear the text in the box.
So, after looking around trying to find out what to do, here's what I've attempted.
I am new to javascript and currently coding a site with scripts that are beyond my level of understanding. The problematic page has thumbnail images that can be clicked on to zoom in. When clicked, the preloaded larger image displays in a div layer that gets turned on. The problem is that ie sometimes does not display the image - the placeholder just stays blank. The script works fine in firefox and netscape (haven't tried safari yet). Since I am new to this and this only happens sporadically, I'm having a lot of trouble identifying the error or a fix. Also, the src for the images is dynamically created from the text name that displays below the bags. This is for content management purposes. Code:
I have function dototal(){ tamount=parseInt(document.myform.amount1.value)+parseInt(document.myform.amount2.value)+parseInt(doc ument.myform.amount3.value); document.getElementById('total').innerHTML=tamount; } The problem is if amount is blank it can't add it -- how can I change it that if it is blank it should treat it as 0?
My Javascript doesn't display an error when the "bid" field is blank but I want it to.Everything else works okay but I'm not a Javascript programmer so I don't know where to begin.
function checkBid(fieldName,minValue,maxValue){ var numberfield = fieldName; if (chkNumeric(fieldName,minValue,maxValue) == false){
(previously posted in the wrong forum and re-posted in this one)Hi there, I have scoured the internet looking for the right code but to no avail. I have gotten as far as totaling up my form but now want to format the amounts and total as currency and also want the values that = 0 to just be blank. I have tried to use the code from other solutions (posted on the net) but I just think it is over my head because I cant figure it out. I thought I was close a few times but wasn't able to bring it on home. One of my issues is using somebody's code and not knowing where in my code to place it have tried exhaustively to solve on my own but there is a point.
whattowrite += fields[2] +fields[1]; How can i force a blank space between fields in js which will be out putted in html textbox with a decent gap between them?
I'm working on this site [URL] and suddenly there is a blank space to the right of the site. As far as CSS is concerned it is not there. I am posting here because I was experimenting with jQuery at the time (I know almost nothing about it). However, I have removed all the jquery code from my files and it has made no difference. IE is giving me a 'console' undefined error.
When a user has entered text into form fields and hits the Save button, the text is saved into local storage. When they hit the Load button at a later date, the text fields are populated.If the user does NOT enter text and hits the Load button, the default empty text fields are populated with the word "undefined." How do I keep the field blank? Because if they do this accidentally, they'll be hitting the back button repeatedly to delete the word in every field (this is on an iPhone).Here is the Load code:
Code: /* * Insert data into form fields from local storage.
I've created a simple code example shown below, the problem is when I run it on IE it returns a blank value, while FF return the selected value. I've built a website using this idea, and the problem is I didn't try on IE until it's too late. This is the code, run it in FF it will work, run it in IE the message is blank !!
