if i have this code: <form><input type=text name="id1"></form> then with javascript i can reference this with this.form.id1, how can i reference something like this:
I have a table which I would like to be highlighted with the click of a button, but I can't seem to reference it correctly. I can make the <td> clickable and function, but when I try to apply it to the button I can't make it reference the td cell, rather than change the background color of the button.The function is:
I am loading a set of icons using an array. The reason for this is that the icon set will be different depending on what some PHP code has given to the JavaScript.
My code currently looks like this.
Code:
var things_to_load = new Array(); things_to_load['header_cursors'] = new Array( 'default' , 'pointer' ); things_to_load['header_icons'] = new Array( '../img/triggers/to-roll/undo.png' , '../img/triggers/add.png' ); things_to_load['header_labels'] = new Array( 'undo' , 'add' );
[Code].....
The problem I have is that the click function gives the error "things_to_load.header_clicks[c] is not a function".
This makes sense as presumably the click function is saving the value and not what that value references.
how I can get this code to save the function not the string referencing it?
I have created an object called list. the object has a method called load and a method called setSelected (it has more, but they arn't impotant here).
The load method prints out table rows like this:
str+="<tr>"+data+"</tr>";
and in the end, inserting str as the body of a table.
what I want to do now, is have an onclick event for each of these table rows, that calls the setSelected method of the current object. so for example, if I'd write this on my page:
mylist = new list(args...); mylist.load(); <div id='associated-div'></div>
that if someone clicks a row in the table that is created in the div, the setSelected method of my list oject will be called.
I'm trying to build a simple "where's the meeting room" page for my work. This consists of a background image of the map, and (right now), a red block absolutely positioned on the map to show where the room is.I'm using an object to keep track of x/y positions for the rooms, i.e.
Code: var rooms = { a123: { x: 100,[code]....
This works, but uses eval() a lot, which doesn't seem like best practice. What's the appropriate way to get the info?Here's the whole page code:
I am experience some problems reading a form variable from a Javascript function. The point with this particular variable is that its name has the following syntax:
<input name="tx_impexp[tt_content:159]"/>
I want to set this var to 1 from my javascript function, so I tried to execute the following line of code:
Error: missing ] in index expression document.frm_1.tx_impexp[exclude][tt_content:159].value=1 --------------------------------------------------------------|
It seems Javascript expects to close down the bracket at the position marked...An easy solution would be to change my var syntax but the point is that I cannot since I am using an already made script and I should not modify it.
Just wandering if this is due to a syntax error defined according to Javascript specification language or there is something wrong with this.
Years ago I created HTML that employs checkboxes and textboxes. I am now writing JS with the intention of adding flexibility and limiting redundancy. I am not sure I truly understand how to correctly interact the two though. For example, one of my scripts have arrays that contain the names of the checkboxes and textboxes, with a 'for' loop to document.write() them to references within the HTML code.This does not seem to be working for me though. Here is what I have thus far (in short):
<script language="javascript"> var teamNames = new Array(3); teamNames[0]="South Africa"; teamNames[1]="Mexico"; teamNames[2]="Uruguay";
[Code]...
I've left out a lot of the code (to include the teamAbbr array, but you get the points. I've tried moving the JS within the HTML body and playing with the reference syntax, but nothing so far.
This has really got me stuck. Below is a distillation of my problem:
This is my function:
function Clear(form) { ???.checked = false; } <form name="myform">
[Code]....
How do I execute the function to clear the checkbox the moment it is clicked? How do I reference that specific checkbox, when there are multiple checkboxes with the same "name"?
The rules (the above is a simplified version of my actual problem. There is much more to my script, which means other possible solutions cannot be considered):
1. I am aware of onclick="this.checked=false", but I cannot use it.
2. The ID for the checkbox is dynamically generated, whereas the entire onclick command must be the same for all checkboxes.
3. All checkboxes must have the same name, and the name must have square brackets.
4. "this.form" must be in the onClick, as it is used by the rest of the 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'm writing a program that involves a network of interconnected nodes (or simply objects in my example below). It depends on being able to access properties of an object's linked objects (a bit oddly worded, sorry)...Problem is I'm not sure how to properly access those properties... see below please.
<script> //This is an example of a problem im having in my own code... //I want to access the name of the object within the links array wintin the object...
I'm trying to use a variable that is passed into a function to to dynamically name an instance of an Object(). I've created a Timer() Object that seems to work just fine... the problem is I can't figure out how to pass in an instance name into setTimer() to create a new instance of Timer() object?? My ultimate goal is to have multiple instances of the Timer() Object running at once. While the code below works it only allows me to create 1 instance of the Timer() Object with the name of tmp. Code:
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;
Whats wrong with this code? i decalre resultArray as a new Array(). Then in a for loop for each resultCount i declare resultArray[resultCount] = new Array(). Then i try putting in values for every resultArray[x][y], but when i go to output the array in another function, everything in resultArray is undefined.code...
I'm not sure if I'm calling it the right thing, but I'm trying to dynamically create a bunch of key => value pairs in a javascript object.
Something like this:
Code JavaScript:
But the console gives me errors, and I haven't been able to find a way to do this. I've tryed putting the keys in square brackets, as was suggested somewhere online, but that didn't work.
in Javascript I need to dynamically assign the values of textboxes from an array. For example, The textbox ids are box0,box1,box2 and the array is [0,1,2]. Here i need to assign 0 to box0 and 1 to box1 and 2 to box2.
I'm trying to update a plugin i downloaded. What i'm trying to do, is make it able to work with dinamically created objects. I'm using the live function to assing javascript events, but i need to know how to assing a plugin dynamically. This is what i have right now:
$("#txtinstruments").AutoComplete("query"); What this does is apply the AutoComplete plugin, to all the objects with id txtInstruments that are already created but, i create more objects with that id on the fly, and i need to assign the plugin to them.
I've got a javascript object is "is" that has dynamically populated properties. I make an ajax call to my database to grab usernames associated with unique ID's and populate the javascript. I can call a property directly like this: aler (is.softUser1) or alert(is.softUser2) and show the corresponding values. However since what is being returned from the database is dynamic I may need to call is.softUser5 or is.softUser8 so I need to do that call dynamically. code...
and that obviously doesn't work.
Is there a way that I can dynamically call that property based on whatever value "user" is?
I am running through a MySQL database using PHP and extracting all of the makes of cars in that database and trying to create a JavaScript array named after each make. Then I am trying to fill each array will all of the models for that make. When I just try to display each Make and Model in an alert box it seems to come up right. And my arrays seem to be getting created but they won't populate with the models (even though my alert msg shows the loops and everything is working).
PHP Code:
while ($row = mysql_fetch_array($result)) { $i=0; //Used so each model is added to the array starting at 0 and ++ $make = $row['make'];//PHP var used to extract data from MySQL
[Code]....
Haven't used JavaScript since a college class a couple of years ago and haven't used it in the real world for even longer. Never with PHP like this. But I am working on this marketing site and need to be able to list products by type according to each brand and as they can be added to a MySQL database it needs to be dynamic. I have the whole thing working by stepping through separate pages using PHP to populate select fields with the data but I want to be able to dynamically add the content to select field using JavaScript so it can all be done on one page and thought that if I could create these arrays on page load then the right information could be selected client side.
