The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Access JS variables for Cold Fusion manipulation

Asked by pbaylis in Cold Fusion Markup Language, JavaScript, ColdFusion Studio

Tags: , ,

I'm struggling to adapt an existing javascript to my CF app. The app in its simplest form can be seen at http://code.iamcal.com/js/jscommerce/demo.htm

Basically, it generates a table completely in javascript and inserts data into the newly created table according to which product is clicked. If you click the "checkout" button, it displays the selected data in a textarea. But, I don't want it in a textarea. I need to access the individual fields out of the javascript and <cfset> them somewhere for further manipulation, e.g. for inserting into a db. But, I can't reverse engineer it and figure out what's going on.

Relevant code is below. But you can also view the entire JS file that creates and manipulates the table from the source above, or I can post it if requiredStart Free Trial

THE CODE THAT PACKAGES THE FORM INFO FOR DISPLAY IN THE TEXTAREA ON THE CHECKOUT PAGE IS BELOW:
 
function get_order_copy(){
 
	var sub_total = 0;
	var items = 0;
	var buffer = '';
 
	// update product rows
	for(var i=0; i<g_products.length; i++){
		var product = g_products[i];
 
		var guid = product[0];
		var name = product[1];
		var price = product[2];
		var qty = get_qty(guid);
		items += qty;
 
		var total = price*qty;
		sub_total += total;
 
		if (qty > 0){
			buffer += name+" ("+guid+") x"+qty+" @ "+format_price(price)+" = "+format_price(total)+"\n";
		}
	}
	buffer += "\nTotal: ("+items+" items) "+format_price(sub_total)+"\n";
 
	return buffer;
}
 
 
THE CHECKOUT TEMPLATE IS BELOW: RATHER THAN DISPLAY IN A TEXTAREA, I WANT TO JUST GET THE DATA OUT OF JAVASCRIPT AND SET THE VARIABLES SOMEWHERE.
 
<html>
<head>
<title>My Shop - Checkout</title>
<script src="basket.js"></script>
<script src="products.js"></script>
</head>
<body onLoad="document.getElementById('order_text').value = get_order_copy();">
 
<div style="background-color: #cccccc; padding: 3px; text-align: right;">
	<a href="products.htm">Continue Shopping</a>
</div>
 
<br>
 
This is as far as my demo goes, but the next step is pretty easy :)<br>
<br>
 
<form>
Order:<br>
<textarea name="order_text" id="order_text" wrap="virtual" cols="60" rows="10"></textarea>
</form>
 
</body>
</html>
