How to implement an Ajax editing in CodeCharge Studio like in the picture above? Is it easy or not? Yes, it’s easy! It takes a half an hour at the maximum. In this article, I will provide step by step instructions. Also, you can download an example here.

alert({}=={}); // false
alert({}==0); // false
alert({}==""); // false

Recently, i had a problem with YUI AutoComplete layout. I wanted it being inline, fixed width and working with different browsers like IE6/7/8, Opera, FF etc. There were some problems that i solved primarily in CSS. More precisely, i needed an inline YUI AutoComplete layout in such a way that i can place autocomplete <input> next to the <label> without a line break. I just set my styles in CSS and override some existing styles and it works ok!

So, problems i had to solve for my needs:

• an outer container is a DIV so INPUT always goes on the next line
• inline-block for DIV doesn’t work in IE6/7
• an outer container has width of 100%
• INPUT is absolutely positioned so an outer DIV is collapsed
• width of 100% makes INPUT 6px larger then outer DIV in IE6
• using inline-block, INPUT aligns vertically on the bottom in IE6
