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 have on submit code that is checking to see if a field has any data. If not, some date fields are updated with generic data. The if statement does what I want it to do with the date fields, but it is overwritting what I have in the field that I am checking with either true or false. I don't understand why this would happen as I am not changing the value of this field with the code, just checking to see if there is a null/blank value.
Code:
if ((document.forms.Master.TrainAssocCourse2.value=null||document.forms.Master.TrainAssocCourse2.value=="")){

I'm getting a value from the database either true/false. I have a alert box that shows it being true/false. I want a checkbox to be checked if true else not. Here is the line of code that I have and it just automatically checks everytime, which I obviously don't want.
$('#returnableCheckbox').attr('checked', $(selectedPlatform).find ('.equipmentReturnable').val())
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?

In the attached code the outcome always defaults to the first test, even if the condition is false. How would I alter the syntax so that both condtions are evalauted?
View 2 Replies View Relatedif i group some javascript into a function that returns false; how could i carry that 'false' out of the function so it can be used outside the function.the example below shows the validate function checks for a condition then returns false if it is met. i want this false to then be passed out of the function to then throw an error in its containing function. (goal to prevent the submitting of a form)i dont want the proceed function to be called, so how can the other function prevent this.Now i realise that the validate function could be incorporated into the top level function but, my form will eventually be quite large with a multiplitude of fields so i need to know how i can call back to functions and use them as objects insteasd of repeating lots of code.

I've got an annoying non-working bit of code:

The first part up to before the 'else if' works. but if the 'w1' has [URL] it still doesnt return true and display the DIV block??
I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.

I am just wanting to use Java to change one value in my code for my project but after having gone through the basics on the web, i seem no closer to finding the solution.I am wanting one JavaScript effect of 'onmouseover' to change the autostart value to 'true' when the preceeding img element is hovered on and to go back to 'false' for onmouseout. I was hoping i'd be able to work out a simple application for an if statement but am now unsure if i'll be able to work it out.Does anyone know a simple javascript that will do the trick?

So for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.

I am wondering about what seems to be a particular quirk in Javascript
that does not allow form event listeners (e.g. "onsubmit=...") to work
properly. In the code below, I would like to set up a function
(doOnSubmit) that is called when the form is submitted.
But there is a "return false;" in the "onclick" of the button. If this
"return false" is removed, the code works as I would hope it would.
With it there, doOnSubmit is never called. Code:
On this page I'm given the impression that stopPropagation is a lot
like returning false:
http://www.brainjar.com/dhtml/events/default3.asp
"preventDefault() Can be used to cancel the event, if it is
cancelable. This prevents the browser from performing any default
action for the event, such as loading a URL when a hypertext link is
clicked. Note that the event will continue propagating along the normal
event flow.preventDefault() Can be used to cancel the event, if it
is cancelable. This prevents the browser from performing any default
action for the event, such as loading a URL when a hypertext link is
clicked. Note that the event will continue propagating along the normal
event flow."
But often, if I want to stop a hyperlink from working normally, I can
simply return false from whatever action I've attached to that
hyperlink. Suppose I have this link:
<a id="link1" href="index.htm">link text</a>
Suppose I attach the function "alertDanger" to this link:
function alertDanger() {
alert("Danger!");
return false;
}
Because I return false, the default behavior doesn't occur. Would there
ever be a benefit to doing this instead:
function alertDanger() {
alert("Danger!");
preventDefault();
}
Perhaps preventDefault is only for those occassions when the code can
not or should not return?
I am building a page with a member login system on the home page. I right now have it so that if the user does not enter a password or username it will change a div to block style and show the error at the top of the page. Is it possible to after 5000 msec after returning false to the form, to hide the div again?
User Does Not Enter Username/Pass
Submit Button Pressed
Error Div Is Shown
Form Results False
5000msec Wait
Error Div Is Hidden
I have been trying for a while, but I either have it disappear and the form takes 5 seconds to get its result, or the form returns false and the div does not disappear.
Here my script :
<script>
$(document).ready(function(){
$('#test1_invalidation_comment__row').hide();
if($('#test1_invalidation_comment').val())

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?
