I'm trying to take X number of elements and organize them into a table.For example, if I had 7 elements, I'd want 2 rows of 3 and 1 row of 1. If I had 15 elements, I'd want 3 rows of 5, and if I had 11 elements I'd want 2 rows of 4 and 1 row of 3.I'm drawing a total blank on how to go about solving this logic problem. Has anybody come across this problem themselves and solved it?
EDIT: Maybe a little more info would do you good. I'm generating an unordered list and I want the LIs to be as large as possible. It sounds almost like calculus, but I need to figure out the largest size of the images I can fit into a given area when I have X number of images.
I am designer and not good in writing scripts and stuffs normally i just copy the codes from the tutorials and make slight modifications.But there something I always have problem. How to organize the scripts in my html. Everytime I spend hours moving the stuffs around until everything works. Is this meant to be like that? or there some priority ..like whats the matter put in the head section or in the body section in the end.
I have written a number of functions designed to return frequency data on 1000 randomly chosen numbers using different math functions for the rounding. I would like to include all of these functions within the wrapper of another function so that only one call is needed to get returns from all of the 'inner' functions. However, while each of the functions works in isolation, the moment I wrap them in another function they stop working. :confused:
The following code is one of the functions 'frequencyWrapperOne' that has been wrapped in the function 'testWrapper'. A call to testWrapper does nothing.
function testWrapper() { function frequencyWrapperOne() {
I have several form in my site, that validate on onsubmit.I call all the validation functions from a file call functions.js.Here is a sample of the code that is working:
I think my brain would have exploded otherwize. Some of the problems have been simple misspellings, but when you have been staring at the same thing for hours it can sorta slip by.Bascially Im not sure if Im using the function command properly. When Submit Details is click it should validate the form and then when Calculate is pressed calculate the form (obviously).I think maybe my var Array table is wrong? And the way the functions are set out doesnt seem it sit right.
Define the function dollarToEuro, which consumes a number of New Zealand dollars and produces the Euro equivalent. The current exchange rate is approximately one New Zealand Dollar to fifty five Euro pence. Code the function in JavaScript. Prompt the user for an amount in New Zealand dollars and display the result.
So far i have done this coding :- var nzd = Number(prompt("Enter The Amount Of New Zealand Dollars", "10")); function dollarToEuro(nzdollar) { return (50/nzd) } document.write(nzd, "NZD =", dollarToEuro, "Euros");
if I have two separate scripts, one that opens a popup window onclick and one that does a tool tip onmouseover, how do I tie them together inline, at the link? And i can put them in the same <script> tags in the head, right?
How do I "merge" the two functions below - checkFromDate() and checkToDate() - so that I only have one function. I want to do the same validation in both text fields, but only have one function that does all the validation.
<html> <head> <script language="JavaScript"> function checkFromDate() { var ToFrom = document.form.txtFromDate.value // Do some other validation... }
function checkToDate() { var ToDate = document.form.txtToDate.value // Do same validation as above... } </script> </head> <body> Start Date : <input type="text" name="txtFromDate" onBlur="checkFromDate()"> yyyy/mm/dd <br> End Date : <input type="text" name="txtToDate" onBlur="checkToDate()"> yyyy/mm/dd </body> </html>
I am learning HTML for the first time taking a self teaching class though my local Community College. Normally this college rocks and has some of the best resources and down to earth teachers that pick books that acutally help folks.
Well they failed and my book take more logic jumps that Stephen Hawkins! :D
So my ultimate question is as follows:
How do I created a function with the following information provided:
Create a fucntion named Mquote that contains the single parameter, Qnum.
My apologies for such little information. I am sure its my oversight that I am unable to locate the answer to my question.
What I am looking for is the base layout for noob java functions.
I want a function to take another function as a parameter, and execute it as a line of code. I put a simplified example below, just to illustrate the idea. Does anyone know the syntax to do this, or is there perhaps a better approach entirely?
// EXAMPLE
doSomething(5, 10, functionA, functionB);
function doSomething(x, y, myFunctionA, myFunctionB) { if (x > y) { myFunctionA(); } else { myFunctionB(); } }
When I click on the "Check All" checkbox, it correctly checks all of the boxes in my form, but I would like each checkbox to also call hideLayer2 function just as what would occur if the user checked the boxes individually. Is there a way to call the hideLayer2 function and pass the correct whichLayer and the_box parameters within the DoToAll function? Maybe there is an easier way? Code:
looking for a way to pass an array to a function. ==================================== <script> function myfunction(arrayname) { document.write("blablabla"+ arrayname[1] +"blablabla"); } </script>
<html stuff>
<script> arrayname = new Array("what", "is", "wrong"); myfunction(arrayname); </script> ====================================
Hello, I have a very large function that activates on one click. It does many individual events that modify my site. They all work seperately but when I put them in a single function they all break. Is there a way, order or priority for putting large things of code in functions?
How can a function be written so that it is reusable within the same form? eg, I wish to place another select menu and its own result span <span="mySpan2"> in the following code (eg. mySelect2, mySpan2) - whichever select menu is chosen displays its own result within its own span: Code:
Can anyone point me to a set of statistical probability functions that will give me (say) the probability for a t-test, an F-test or a X2 test. I did find some in the wild on the net, but I am unsure of the legitimacy of using them.
I want to find out what is the file name of the page that a user is currently viewing (for e.g. the file name of the page where I am composing this query currently is newthread.php). If the file name is Edit.asp, then do something else......this is the
(this is the onLoad event function)function getFile(){ var strURL=window.location
//since the file name will be at the end of the URL, I am using //a negative number as the start parameter in the substr function
But the above doesn't work. In fact, some of the JavaScript string functions I tried (like match, length etc.), none of them seem to work since the string has been derived using window.location. Why? Doesn't JavaScript consider the URL of a page as a string object?
I'm having a problem. I was able to get the edit working fine. I was able to get it to hide the current div and go to a different div. When I combine the two, the edit works but I cannot go to the different div.
I am writing a simle extension on Google Chrome. But chrome's extension API is not powerfull enough for my extension because i need file io operations for local files. That's why I need to call functions from dll which i write from javascript.
<script type='text/javascript' language='javascript'> var obj = new ActiveXObject("plugin_proxychanger.dll"); var vResult = obj.plugin_header_class.plugin_header_func_read(3); document.write(vResult); </script>
I get this error on every browser: ReferenceError: ActiveXObject is not defined I research it on google and some users told me that i need to write a COM dll. But my dll is .net(2.0) because I don't know how to create a COM dll with Visual Studio 2010.
I'm struggling a bit with trying to make sure when I set an event handler (or listener) on some element which calls a function I've got elsewhere, that the function can't see necessary vars because they've already been garbage collected.I'm following the type of setup as in Simply Javascript or the Javascript Live course.o I have stuff like this
