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!

Ajax function unable to get object properties

Asked by Paul_Jarrett in Asynchronous Javascript and XML (AJAX), JavaScript, Firefox Web Browser

Tags: ,

I am trying to knock up a little Ajax-y method or two, just something nice, simple and reusable. All it should do is take the resonse and vomit it into the innerHTML of whatever element you specify. What I have works a treat in Firefox however Internet Explorer errors with the typically useful text

this.objElement is null or not an object.

I'm guessing this is something to do with the fact the function is called from the readyStateChange Handler so the object is recreated in a fresh instance? ...thou now I've guessed I'm sure you'll make me look silly....

Thanks for your helpStart Free Trial

	this.objElement;
	
	baseHandler.prototype.setTarget = function( objElement ){
//		I'm sure it should be this way round, but the browser knows what it likes...
//		this.objElement = objElement;
		this.handler.objElement = objElement;
	}
	
	baseHandler.prototype.handler = function(){		
		if(http.readyState == 4){
		var response = http.responseText;
			this.objElement.innerHTML = response;
