How To Get Blank Amount Treated As Zero In Add Function
Mar 15, 2009
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?
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?
------------------------- chkbox | name | number ------------------------- radbtn | MJ | 234123 radbtn | MD | 343543 radbtn | AB | 453466
Is uncertain that how many info will appear as its from database. I am able to enable the radbtn with chkbox by getting radbtn name. How can i enable only the selected radbtn textbox under name and number in order for user to edit it?
Hi All, I am trying to program a web based cash register/POS application. I would like to use a function to format the number in the "Amount Received" text box.For Example: if someone typed in 2000 it would automatically change that to 20.00
I would probably be triggering the function via onkeyup so it would actually change it on number at a time. 2->.02, 20->.20, 200->2.00, 2000->20.00 ect.I know I could do it in php when processing the form, but I would really like the number to be already formatted when the form is submitted.
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:
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?
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 want to make a hooverbox, which is shown when the mousepointer is not moved for a amount of time.
When the hooverbox is shown, i will do a server request to retrieve the information for the hooverbox.
I was thinking of using document.onmousemove and a infinit running while loop comparing the mouse positions. Is this the way to solve it? (pointers/samples are welcome ;-) )
Im using a vb script that will show the latest x forum threads on forumhome but i would like to be able to restrict how many characters it out puts so after say 150 chars then the 3 dots would appear.ie. This would be my forum thread ti ...Heres the script im using
<if condition="$vbulletin->options['externaljs']"> <!-- show latest active threads --> <table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0"
This is probably a really simple question. Is it possible to initialize x amount of variables. Like someone enters 10 into an input box and it makes 10 variables called variable1, variable2, variable3, etc.How would you name them?variable + num = 0; ?

I'm a newbe and but I was to become a good developer. I'm currently working on a script that will pull call information from a data base using PHP. I managed to create the portal where this information is displayed.But I just need to add some kind of alert where the call has been on hold for about 20 seconds. Is there a way I can do this. The script that I have created has Javascript. can you guys help me with the code to alert when the 20 seconds have passed.
