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.
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
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 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?
function generatePurchaseFields(dom) { new Ajax.Request('/control/?page=tldmaxyears&domain=' + dom, { method: 'get',
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: }
I am trying to test the id of three input boxes so that I can capitalize the first letter.
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?
I need to give two separate alerts depending on what the user clicks when they click the "Submit" button. I am using a confirm box. If they click "OK" it thanks them for their order. If they click "Cancel" it should go back to the form. I have written the code that I thought would work but it will not.
function confMsg(){ var s s = confirm("Click OK to Submit Order. Click Cancel to Cancel") if (s=="true"){ alert("Thank You for Your Order!") else return; }}
For the first time, I'm attempting to write a small Javascript program using one on the online reference sites. I need some confirmation as to the behaviour of the break statement.
In the following code:
for ( row = 0 ; row <= 7 ; row++ ) A <---- { for ( col = 0 ; col <=7 ; col++ ) B <---- { if ( check ( row, col ) == "pass" ) break ; } } }
Where will control pass to once the break statement is executed? Will it continue with the first 'for' statement (A) or the second (B)?
Also my 'check' function needs to pass an indication as to it's success or failure. It does it by:
return ( "pass" ) ;
Am I doing it correctly?
Any links to useful reference sites would be welcomed.
I'm trying to stop my script running if someone mouses over a link with the class .focus. The code: $(document).ready(function() { window.setInterval(function() { //Every 3 seconds do this function if ("a.focus").mouseover(function() { //Do nothing }) else { $(".list li:nth-child(3)").children().toggleClass('focus'); //Remove class from <li> #3 $(".list li:last").css("height", 0); $(".list li:last").prependTo(".list").animate({ //Put last <li> to the top of the list and animate the height from 0 to 48 height: 48, },200, function(){ //Animation Complete }); $(".list li:nth-child(3)").stop().children().toggleClass('focus'); //Add class to <li> #3 }}, 3000);});
