Dynamically Creating A Unique Variable Name For Elements With Same Class Name?
Aug 31, 2010
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 form that asks a simple question: "How many XYZs do you want to create?" Then, for every XYZ, it should create several new labels/inputs in the form.
That is, every XYZ looks like this: <div id="xyz"> <label>Whatever</label> <input> blah blah blah </input </div>
I looked into .each() and .live(), but I can't wrap my mind around how to do this.
Here's my problem: I need to create a variable name dynamically, made up of a string (say "var_name_") and an integer. Ultimately I want something like this:
var_name_1 = 'whatever value I want' var_name_2 = 'whatever value I want' var_name_3 = 'whatever value I want' ... var_name_N = 'whatever value I want'
But the actual variable names are determined at run-time, so I can't just hardcode them.
Any suggestions? JavaScript doesn't seem to have a Variable type, so I can't just cast a string into a var...
I am trying to insert a row with values bases on input fields on submit. However when you submit, it is adding table rows to every table in the document. I have been struggling with this. I have tried using $(this), .parent(), .parents(), .closesest() etc.. [URL]
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.
I'm interested in getting an array of unique class names of all option tags under a specific select element. I'm imagining something like this (which does not do what I want): $ ( '#select_id option.class' ); What's the correct way to do this using jQuery?
Let's say you have two elements, and you know their IDs; is there a way to select them both at the same time; something like $('#test #test2')?I realize I could just select them both on two different lines and apply the same function, or use class or something to track them down; but sometimes I just want to grab two elements by ID and do the same thing to them. I assume I'm just missing the syntax.
Im building a small feature where users can create a page. They select an element they would like to add from a select box. When they select it it is automatically appended into the preview div. The problem is that they can choose to add any number of divs, p,s etc to this preview div and i need a way of giving them all unique ids so i can use them later.
This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code: var flag; for (i=0;i<=pdfs.length-1;i++) { flag = 1; for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
rote a bunch of Javascript classes for this framework I'm working on and want to be able to create instances of the class using just it's name string. For example: Given the following class
I have this code that when just enclosed in a <script> works:..dto = new window["imenus_data"+(x2=x2.substring(6))];but when i put this code in a class and access the function:
I'm using the following code to create a quick and dirty search tool for a site we're building at work as part of an RFP.My issue is that rather than creating a new window for the results page (which is what it does now), I'd really prefer that a new div be dynamically created on the page where the results would be placed.Maybe that's not possible? At the very least,how to make the results display in the same window rather than opening a new one?
<SCRIPT LANGUAGE="JavaScript"> var item = new Array(); // "Page Name","path","Page Title","Many,Key,Words","Descriptive Comments"
I created <a> tag dynamically and attached event to it.
Code:
var link = document.createElement("a"); link.setAttribute('class','devNodeStyle'); link.setAttribute("title",device); link.setAttribute("href","javascript:void(0);"); link.attachEvent("onclick",openDevDetailWindow);
"attachEvent" is working only in IE. How to make that working in other browsers like Chrome/FF?
Somehow, the isLoaded property doesnt seem to be set to true when i create an instance of the class. I tryied passing the object instance through an argument ... this.xml.onload = this.fileLoaded(this) ... MyClass.prototype.fileLoaded(obj){ obj.isLoaded = true;}
I'm creating a javascript class that draws triangles for a project I'm working on (none of the other vector solutions for triangles were satisfactory so I'm writing my own).
Anyway here is a small snippet of code:
Code:
The idea of the code is to create a small div in the middle of the triangle that a user can click on, pretty basic stuff.
Problem with highlighted code is, on their own they work, together they dont.
IE, if I only set the LEFT of the div, it moves across the screen to required position.
If I only set the TOP of the div, it moves down the screen to the required position.
But BOTH together (as above) just make the div dissapear somewhere. Weird.
I know this is not strictly related to jquery but I don't know how to make it works. I'm working on a function that has as variable an array and for each element I need to create a piece of code for an other function. For instance when the array contains [0,1,2] I need to call
im trying to create a script for greasemonkey but its still written in javascript. so here is what im trying to do. Ive got a dynamically created division that aligns to the right of the browser window. Now im trying to put links inside it as you normally would with like a document.write statement or other methods. The only problem is, any method i try wont work for me. heres my code, maybe someone could give me some things i could try.
I am trying to create a function that creates an array comprised of filenames based on a given range. I.E if 2-8 is selected and a foldername of UMCP/ and a common name of college is also given, the function should return and array such as [UMCP/college2.jpg,UMCP/college3.jpg.....UMCP/college8.jpg]. Here is what I've got but the alert that should tell me the filename of the first image says it is undefined, how can i fix this?
function getArrayPhotosNames (total,count,first,last) { /*window.alert("get Array Photo Names");*/ var folderName = document.getElementById("photofold").value; var Alias = document.getElementById("commonName").value;
I've got an input with a value. The input is called 'command2' and I want to send it's value to the 'rover2' object (although I don't know if that object exists yet). I test and say if(rover2){... and if not then I create the object/if so then I insert the value.Question is: I want to do:Code JavaScript:var rover2 = new Rover();but I want to pass the name of the new object by association, so in effect:Code JavaScript:var "rover"+i = new Rover();How would you do that? So that the objects and their names are generated dynamically (or [perhaps a better explanation] so that the string value of a variable can be used as the name of new variable/object)?PS Bonus marks: If I hold HTML fragments as an object and those fragments include inputs, is the value of the input collected as well? i.e. if I have
As part of my form I have a box for the user to input the number of text boxes needed. I already have the page creating the textboxes but do not know the IDs of each text box. Once the user adds textboxes they can click add again to create more. If the user previously added 3 textboxes and now enters 4 I want the program to just add one more instead of 4 more.
I want to find a way of using canvas tags that are created at runtime. I went about this by trying to change the id of the tag, ONLY to find out that javascript did not like the fact that I was using numbers, even though I converted to String first... var count = 0; for (var item=0; item<20; item ++) { if (count%5==0){ document.write(" ||| "); } var canv = document.createElement("canvas"); canv.setAttribute('width',300); canv.setAttribute('height',300);
num = 505; aStr = num.toString(); // does NOT do the job for some reason !!!??? aStr = 'canvas'; // this works... canv.setAttribute('id',aStr); document.body.appendChild(canv); count += 1; } var C = document.getElementById(canv.getAttribute('id')); if (C.getContext) { makePlot(C); // does the plot to the canvas }
Im developing a script for dynamically creating html table structure so that from the input that has been given to the function it will fetch the values one by one and will create the structure. My problem is i want to add attributes to the elements created. sample code attached.
here the element name will be get from the parameters passed to the function. i want to verify whether the line in bold is correct or not coz the id is not updated in output.
I'm a JavaScript noob, and I'm playing with it. I have some code which created a div inside another div by using the innerHTML of the outer div. That had an onclick event which worked fine. Now I'm trying to create the div as an object, so I'm doing something like this:
Code JavaScript:
var obj = document.createElement('div'); obj.id = "object"; obj.onClick = function() {alert("Clicked");}; obj.innerHTML = "something"; // an img tag in the actual code document.getElementById('objects').appendChild(obj);
The new div is shown, but clicking on it does nothing. (I originally had another function, but changed to the alert for testing.)
