What the join() method really does... I didn't quite get it. It said that it joins the array elements into a string, but isn't it already strings? how would you use this method...
var fruits = ["banana", "apple", "pear"];
document.write(fruits.join());
What did that do, how do use this method.
How can you join two numbers together in javascript, like you would join two strings?For example, if you have two variables, with 1 stored in each, how can I join them together, so I get 11, instead of 2?
I have two element sets: $(".contentBox") and $(".referencesImage"). How can I join the elements in this sets? I would like to join the sets, since I'm adding the exact same hover function on both element
i want an html code or javascript equivalent for this particular case.i want to put two input values into one.in other words, join them together..example:
I am working on a project which requires a method to join or split multidimensional arrays according to its arguments, which would be string delimiters for the various dimensions of the array.
An example of the join function might be:
The split function:
This would turn 'str' into an array like this:
I think I may have found the problem (but not the solution) - it looks as though javascript won't perform a method on an array which is part of another array. Firefox error console gives me "arr[0].join is not a function".
what i'm trying to do is have it when once a user clicks on a banner the join raffle button will show after clicking on the banner, along with opening up a new window to the link the banner had. I've been trying to set up a onclick event to do this but haven't had success This is the code ive tried using.
I need to capitalize user input from a text field by passing the data to an array and using the split() method, then then join() method and of course toUpperCase. I need to accomplish this with a loop. I only have a crappy ebook and haven't ever been in a java classroom.
Here's what I have which is not at all sufficient. I learn best from examples, so here I am... <HTML><HEAD> </HEAD><BODY> <FORM ACTION="#" NAME=strn> Enter lower case text <INPUT TYPE=TEXT NAME="txt1" SIZE=20> /
The following lines of code are just my attempts at guessing javascript logic/syntax function arrays(){ for (var i=0; i<secondarray.length; ++i)} firstarray=getElementByName.txt1 var secondarray =firstarray.split(separator[" ", 40]).toUpperCase(); /var secondarray.join([""]) <BR><BR> <INPUT TYPE=BUTTON VALUE="Convert to Upper Case" onclick="document.strn.txt2.value = document.strn.txt1.value.toUpperCase()" <BR><BR> <input type = "text" NAME=txt2 size=20/> </FORM></BODY></HTML> I know this much .array = string.split(separator[, limit]);.
I'm trying to do something, but I don't know if it's possible. Basically, I want to have a public static class method that could access a private object's method. I would like to be able to do :
Class.method(InstanceOfClass);
The method would then access a private function from Class by doing something like
function method(param) { param.privateMethodOfClass(); }
I've done a lot research and experimentations but just can't come up with a solution... I don't even know if what I'm trying to do is possible.
Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:
function Core(){ var obj = {a : 'a', b : 'b'}; var num = 1;[code]....
//right now none of the above would work but it's more convenient than using the call alternative.
} Core('dom','event','ajax');
Why did the designers of the javascript scripting language make this decision?
I'm a relative novice at java script. I've been working on a google map that can be found at: [URL](way too much code to post here). Each of the makers on the map has s particular set of information that pops up in a window when it is clicked, including a hyperlink called "join this group." Right now clicking on that link merely takes the user to the form at the bottom of the page.
What I would like the link to do is to both take the user to form at the bottom of the page and automatically select from the drop down menu the group associated with that particular "join this group" link. For example, if a user selected the marker representing the Neighborhood, Beverly group and then hit the join this group link, the drop down menu would automatically select the Neighborhood, Beverly (Pless) for them. I suspect this involves using java script to pass a value. I just have had no luck getting it to work.
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.
Is the form below a valid method of changing the id of an XHTML element, specifically the one actually being referenced? It does not seem to work for me.
function doSomething () { var obj = new Obj(); obj.foo = bar; doSomethingElse(obj); }
In function doSomethingElse I want to create the following line of DHTML
<div return true;">
What I want is for onClick to be defined to be the execution of the foo method of obj.
I tried document.writeln ("<div + obj.foo + "(); return true;'>");
What I get is the source code for bar stuck into the middle of the string. So how do I get just the name of the function bar in the string? Or ultimately, how do I get the handler to be bar in the DHTML?
While submiting the form elements, if the GET method is used in the <form>tag, the data is submitted as a query string.I think there should be restriction in size of data submitted by the browser IE. Does any body know the exact details of it?
I only use forms as input and output to javascripts. Many times I use innerhtml to write to a <div> for output. I don't know of an alternative for input.
I sometimes have problems if I use method="post" and just leave it off. The browser tried to reload the page after the script ran. Sometimes I am able to even leave off <form> and </form>. Could someone explain when form and method are actually needed?
I responded in comp.lang.javascript to "Adding to fields with onchange". I had to leave "method=" out to get it to work without trying to reload the page.
Is there any way to call the new operator as a method (function)? The reason is that I've got IE as a COM object (Imagine I've brought up IE using VB) and it's easy to call every method of any DOM element (including window). But if I want to create a new object, then it's more complicated. Of course I could always execute js code (using window.execScript) which will create the object and save it as a variable on the window object and then pick it up from the COM creator, but really...
Consider the following page snippet which nicely adds an option to the empty select element. Of course, I could use the W3C createElement, addChild, muckWithDOM approach to avoid the execScript, but both of these are going to add huge amounts of time and substantial complexity to an otherwise one liner:
<form method=pos action=''> <select name=sel id=sel></select> <script type='text/javascript'> var sel=document.getElementById('sel'); sel.options[0] = new window.Option("foo", "bar"); </script> </form>
Can't I do something like window.Option.newInstance("foo", "bar") in place of the new window.Option("foo", "bar") ?
I am pretty rusty with javascript and I am trying to make a webpage that will basically act as a wrapper from one webpage to another. What I mean by this is that I will hit this page like: webpage.htm?Param1=... and I will take the passed params and post them to another page. I have the post part working, but I was just wondering how I can use just Javascript and read those values passed to this webpage. Is this even possible?
I am experiencing some rendering problems when dynamically changing CSS (width) with both Internet Explorer and Firefox. In some cases it is just in IE and in other cases just Firefox. When resizing the browser (1px is enough) everything is positioned correctly again. Is there some repaint method that I can call?
The last time I tried to ask this question...Google Groups screwed up my message and there was no subject (sorry for that - I know it's annoying).
I'm trying to learn how to develop a plug-in that allows users to display data from one site in a third party site, like Google Adwords or the Digg counter for news stories. I took a look at Digg.com and found the following:
It looks like digg is doing the following to show the number of "diggs" for a story on your website. On my page I would have the following:
