i have the following:
a1="asdf"
how can i check in an if statement whether contains a numeric only value and if not then alert.
I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function.callback should be a string so why is it saying otherwise?

For example:
If that is not possible (which is probably not its not working with me) how would i go about displaying that?
I am working on a script that seems impossible to work. I want to click on a link, and if the .text() is the same as a classname of a div, I want to do stuff with the div. The problem is that I can't imagine how to set up the if-state. Right now the script is like this:
$(document).ready(function(){
var filterTrig = $('#sortPort a').html();
$('#sortPort a').click(function() {
$('.listItem').each(function(){
if (!filterTrig == $(this).hasClass(filterTrig).html()){
$('listItem').addClass('test'); //later on, animations
}} return false; }); });
The script runs here: [URL]. I have turned off all other javascript to work only with this, if the site seems broken. The filterbox to the left will filter the div items listed to the right. All "boxes" in the list is a div with classname listItem + classes equal to the a.text() in the filters (leftbox). It is thoose divs I´m trying to animte with clicks.
I'm trying to pass this string and I keep getting the "missing ; before statement error" which I know means I not escaping something or something,
content='<a href onclick="javascript: document.getElementById 'searchbox').style.display='inline'">here</a> to enter your address' +'<div id="searchbox" display="hidden"><form action="javascript:getDirections()">' +'<input type="hidden" SIZE=40 MAXLENGTH=40 name="saddr" id="saddr" value="" /><br>' +'<div>';
my webstie allows users to change the color of the background, so to keep the text readable I have it changing as well.the color picker I am using has text boxes with rgb values 0-255 for each.I am trying to get one bit of text to alternate between red and blue with the conditions
Code:
if(blue>green && blue>red)

I want to know if there is a way to return ajax call as html value and not plain text, ie all html formatting will be displayed.
My code:

$(function()

String returned from webform4.aspx is html formatted but jquery displayed it as plain text. Is that anyway to display it as html string ?
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;
var qualname = "discountqualifier" + j;
qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...

I need a simple, quick and efficient way to logically branch if I find a string is contained in another string in jquery Most other languages this can be resolved in one or two lines and it would be readable.

View 11 Replies View RelatedI have made a basic form, and I need to combine three values within my form, then create an md5 hash of this string.Then assign it to a hidden variable.My form is here...
Code:
<p>
<label for="firstname">First Name: </label>
<input id="firstname" type="text" name="firstname" /><br />[code]....
Or I have created a pastebin of it here, for easy reading: http://pastie.org/1171757.So I need to be able to combine the three values into a string, create a md5 of the string, then call the value of the string into a hidden value all before posting the form.
I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.

I am reading the ECMAScript specs trying to figure out if the next
line is a legal statement or not new Foo();
I think the above code may only be legal as an expression and not as a
stand alone statement. Would this make the above a bug?
Douglas Crockford's JSLint will choke on the above line of code and
stop parsing. All the browsers seem to accept it as ok and work as I
expect: the returned object just doesn't get assigned to anything.
The time I have used a line like the above is when the constructor has
side effects and the "class" keeps track of all its instances.
Any ideas what is right or wrong in this case?
I have several text fields on page that I would like to make calculations based on if there is a number input in one of the fields.
So, if the price field is populated, the sale price field would populate using a function to do the calculation.
Now, how do I write the code for this to occur? I know how to get the function to fire based on clicking a submit button, but not sure how to do it simply based on a number keyed into the one field. Is this possible and if so, how?
I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.
What is the correct construct for accessing "pageYOffset" in another window?
I've tried this, but it doesn't work:

It's been a while since I've worked with javascript time comparison,
and I was wondering how I can say "if time < 15:30"?
The semicolon looks out of place to me, and indeed it has caused an
error.
I remember using if statements with null in it. For example, at one
point I used this:
if (value == null) {
value = "something";
}
document.write(value)
However, this script causes an error in any browser. Why can't it
correct the value like it should?
For the following two snippets, they can all pass Firefox.However, I would like to know the rule of thumb when I have to use ; to indicate the end of

I have a two fold question:1) Why would my while statement not be workingI have cleaned up my code a little (although not perfect) but my while statement is not behaving, it does not output any numbers on a console.debug (using google chrome, or any other browser for that matter) which from my understanding it should?and 2) Slightly out of the remit of this forum I suppose, but this code is quite lengthy and I know there are ways to make this more efficient I just dont know what they are?

This is my first time using the switch statement. I would appreciate your suggestion on how to do this properly. I am trying to get customer age which is (age) and compare it with the monthly rate then the text msg will display in the textarea. Also, I am having trouble figuring out how I can defined my monthlyRate in the switch or do I need to this outside of the switch? Code:

The fname and lname work fine but mi does nothing and I get no error is this because of the if statement or the fact that the mi only has one character?
