JQuery :: Dynamically Declaring Functions - 'array' Variable Contains Strings Representing The Id's Of Different Elements
Oct 12, 2010
Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
(the "code" below is pseudo code, just to get the idea across)
Here's what I currently have:
var bill = new array[20]; var sam = new array[20]; var nancy = new array[20]; var Oscar = new array[20];
I'm assigning objects to them (ie Oscar[5] = new objLabel() This seems like a kluge, however. Here's what I'd like (again, pseudo-code)
var Objects = {bill:null; sam:null; nancy:null; Oscar:null}; var theObject = new Array of Objects[20]; // yes: i know that's wrong... and that's the part I'm having trouble with
so that I can do something like:
[Code]....
Just seems to me that keeping a single array of multiple objects is likely to be less error-prone than multiple arrays of single objects... But I don't have the syntax right... or can it be done in JS? If it's doable, would someone be kind enough to show me how to declare and access that example?
I have a php script which calls a javascript function with a parameter. I am having trouble getting this parameter act as an array inside the javascript function:
JS sees fruits and vegs as a string rather then an array, so if I try to output fruits[0]; it gives me the entire string rather then seeing it as an array and giving me the first element.
I am doing a Validation for Form "Text input". If the user leaves the input empty, a function is starting to run. If the field is bigger than 1 - so it doesn't get into the function.
The problem is: The first time, the user left the input empty, function ran, and I got the alert - that's OK. Second time, The user added 10 in the AGE input - And again he gets the Alert - But he should not.
Note: Age input value, returns from a different function (calc) to a var called: result.
I am probably going about this all wrong, but I'm not sure how to do this.Basically I need to create a unique variable name for each element that has the same class name and set each one to zero.I thought I could just concatenate the index value to a variable name to create unique names. Something like:
$('.toggle-trigger').each(function(){ var toggleTriggerIndex = $('.toggle-trigger').index(this); var t + toggleTriggerIndex = 0;
I have variables coming in from JSON files via AJAX calls. Each file will have 3 variables for different background colours. Depending on which button is clicked the background will change colour to the value specified in the JSON file.
I have this code for HMTL5 Canvas, however this is a JavaScript directed question not a Canvas question.
<script type="text/javascript"> var c=document.getElementById("myCanvas"); var cxt=c.getContext("2d"); cxt.moveTo(0,400); cxt.lineTo(50,a); cxt.lineTo(100,b); cxt.lineTo(150,390); [Code]...
That will draw a line graph, however I want to get the coordinates from a variable in the URL. So it may be example.com/a=500&b=600 . How would I retrieve these two variables and then insert in to they're respective places?
I was working on this problem that asks me to return an array of scores for each string (only for its content part, not URL) in the global variable, which is an array. For example, alert a score of 0 if the string z is not found, 1 if found once, and 2 for twice. My problem is that I can get the code to alert if it has found the word (ex. "the"), but I cannot manage to :
a) Assign separate scores for each string.
b) Make the search case insensitive i.e. "the" will appear in 0,1, but not in 2, where it is capitalized
[CODE] var c = ["[www.facebook.com] Facebook is the best social networking site to coccent with your friends. ", "[www.google.co.uk] Google is the worldwide search engine. ", "[www.bbc.co.uk] The best news source for starting your day. "]; function findScore(z) {
how to trim strings in Javascript with variable lengths? For example:
My Option 1 (+$10.00) Short Option (+$5.00) Really long Option
I only want to trim off the (+$10.00) on My Option 1 and the (+$5.00) on Short Option. No trim necessary on Really long Option. When I'm done I want to be left with:
a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.
Im initiate with jQuery now and trying to create some elements and, after that, create functions for this. What i do is:
[Code]...
function" works fine, but when i try to execute the "close function" i cant get he result. Its seems like after create element, i cannot use any action with jquery for. I know, probably this is very simple, but i need to practice step by step.
I have a table that i load into the document via ajax. the table shows a list of times. every row has a button that when clicked should call another AJAX function. However when clicking the link nothing happens. If I put a link in the original document myself and ask it to do this, it works fine, but becuse this is generated code, this option will not do.
I have a single javascript file that contains all of my javascript functions. Each of the these functions are particular to different pages on my entire site. How can I create logic that will only allow those functions to work when certain elements or identifiers are present on a page?
So in the Tutorials:How jQuery Works, I've noticed that you can make a call to .get like this : $.get('myhtmlpage.html', myCallBack);
I've also noticed that in the docs jQuery.get() is described as jQuery.get( url, [data,] [success(data, textStatus, jqXHR),] [dataType] ). My question is, in the above example, the callback function is the second argument, whereas in the docs the second argument is data, and the third is the callback function. How does this work? Also, what does it mean when the arguments are laid out in an array-like fashion with commas in the square brackets? i.e. arg1, [arg2,]...
I've recently started developing javascript using jQuery and so far I'm really enjoying it.Being a professional programmer (mainly C, C++, java and python) there is one thing that's been puzzling me regarding variable scope and unnamed function declarations. Let me exemplify:
------------------------ var sum = 0; $(xmlobj).find("item").each(function(){
I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I have a simple problem and cant seem to figure it out. I have a function in the body.load function that is supposed to highlight rows in my table when i mouse over them. When u refresh the page, the function works properly. When I dynamically add new rows to the table using ajax, I get no response.
