You are missing the container div to display the data, in your javascript code you are referencing #container-div but it does not exist inside your html code. Typically you don't have to write any html code like you seem to be doing (or is it the result you displayed?), except for the grid container itself. Try simply adding or replacing with this code in your html body: <div id="container-div" style="width:600px;height:500px;"></div> You can see a simple example from SlickGrid here: https://github.com/mleibman/SlickGrid/blob/master/examples/example1-simple.html

Functions prototype properties have initial values that include constructor. You can try it:

function Foo() {
}

assert(Foo.prototype.constructor === Foo);

When you overwrite the entire prototype with an object, youre clobbering that property. ({}.constructor === Object.) Just assign new properties to it instead:

Foo.prototype.bar = function () {
    console.log(this.a);
};

Well... after spending some time on this I found the culprit. Loading Javascript files, doesn't matter if it's a local or remote file, minified, etc, adds significant overhead to the load time of the webview. Also, it does not matter if scripts are placed in the or before the tag, results are pretty much the same, at least in my case.

One solution I found was to use head.js to load scripts in a non blocking manner. It definitely helped. Anyway, just posting this for others who run into a similar situation.

@peter documentation can be found here: headjs.com however, I am now using another method to combine and minify all my js/css files.

the "childNodes" part did the trick! I used my original code, added a 3 sec. delay after "open location", and after "do Javascript", I copy pasted your code code after "execute javascript" -- worked perfectly. Thanks a lot!

You are likely trying to get the element before it exists (the page just started loading). Try this:

do JavaScript "window.onload=function(){document.getElementById(\"gn-store\").click()}"

Unfortunately, that still results in "missing value" tell application "Safari" open location "apple.com do JavaScript "window.onload=function(){document.getElementById(\"gn-store\").click()}" --> missing value end tell Result: missing value

No. I tried filling in my element, changing it from "ByClass" to "ById", and went back to "getElementById". I got nothing. I also attempted that code, multiple times (in the address bar, and with the modification in the comments); I couldn't get it to do anything.

You're changing the constructor of Foo() by redefining its prototype to object {}.

Foo.prototype.bar = function () {
   console.log(this.a);
}

Ideally you should present the javascript that you have already written, and explained what it does do, and what is missing. Having said that, I recently finished work on a similar project to what you describe, so had the following results handy.

Does this jsfiddle do what you are attempting?

There are two key components. The first is in defining the text elements (here I append them to an SVG element):

var text = svg.selectAll('text')
    .data(force.nodes())
    .enter().append('text')
        .text(function (d) { return d.name });

Here I'm assuming that the nodes[] array contains objects with a .name property that is to be displayed.

The second component is to translate the text elements to their appropriate positions, inside the tick handler:

function tick () {
    text.attr('transform', function (d) {
        return 'translate(' + d.x + ',' + d.y + ')';
    });
    // Other code for nodes and links
}

See the jsfiddle for a complete working example, including commented code that should allow you to add images at the nodes if you want to try to reproduce your sample image more closely.

I think you cannot pass the getElementById method into an 'if' condition to get a bool, You might want to grab the result into a javascript variable and check if it is null like this :

//getting all the divs who have the class 'errormsg'        
    var div = $('.errormsg');        
    if (div != null) {        
    //do nothing         
    } else {        
    //redirect to a differnt url        
    }

You have two issues with that code

document.getElementById
document.getElementByID

Second, .childNodes[0] will be undefined as the element with ID 'gbqfq' is the input element itself. It should read document.getElementById('gbqfq').value
