Top jQuery Tips for Beginners
0Hot Tip #1: Access Elements by Javascript Array Indexing
Application of a selector creates a Javascript array which can be used for accessing DOM elements with array index easily.
For Example:
var element = $(“img”)[2];
will set the variable element to the second <img> element in the matched set of document’s all <img> elements.
Hot Tip #2: Create Union of Elements with Multiple Selectors
Union of multiple selectors can be created by listing selectors separated by commas ‘n a s’ngle call to $()
For Example:
$(“img,p”)
will match all <img> and <p> elements, while the following matches all <div> elements with a title attribute and all <img> elements with alt attributes.
$(“div[title],img[alt]“)
Hot Tip #3: Be Careful with not() and remove() methods!
.not() method removes elements from the matched set while the .remove() method removes the elements in the matched set from the HTML DOM.
Rss to Email Te Free and Easy Way
0FeedBurner is probably the best option to start with for most blogs. It’s free and gets the basic job done. The only reason you might want to upgrade to FeedmailPro is the same reason people upgrade to Aweber: you might need some more advanced features.
Here are a few signs you might have outgrown FeedBurner:
1. If you want more flexible scheduling. The only option in FeedBurner is to send daily emails and this can overload your subscribers causing them to unsubscribe. With FeedmailPro you can schedule delivery to weekly or whatever you’d like.
2. If you want a “thank you” email to go out with a sign-up bonus or ebook after someone subscribes. Many bloggers use sign-up bonuses to increase readership and you can’t do this with FeedBurner.
3. If you want to send out the occasional email blast to your list that isn’t More >
Setting Focus to an ASP.NET Control – Set Focus After PostBack – After Submit – on Page Load in ASP.NET 1.x
0Management of control focus is one of the common tasks when building web applications with effective and friendly user interface. In order to set focus on a certain control such as textboxes, buttons dropdowns after postback / after submit / on Page Load in ASP.NET 1.x, we can use a dynamic javascript block that facilitates Javascript’s focus() function.
private void SetFocus(String controlID) { // Build the JavaScript String System.Text.StringBuilder sb = new System.Text.StringBuilder(); sb.Append(“<script language=’javascript’>”); sb.Append(“document.getElementById(‘”); sb.Append(controlID); sb.Append(“‘).focus()”); sb.Append(“</script>”)
// Register the script code with the page. Page.RegisterStartupScript(“FocusScript”, sb.ToString()); }
For the above code, you need to pass the control’s id as the parameter, then define the Javascript function in a string variable then call the Page class to register the script.

A strong password should:
- Contain 8 or more characters

Methods to Create Equal Height Columns
0Back when tables were used for layouts, creating equal height columns was very simple. All you had to do was create three cells in a row and you have a layout with equal height columns. The method for creating equal height columns isn’t as straightforward when you use CSS for layouts.
This article discusses some methods to create equal height columns that work on all major web browsers (including the infamous IE6). All of these methods show how to create a three column layout.
Create a layout in which all the three columns assume the height of the tallest column.
Method 1: Using display: table Attribute
In this method we use a list or one div enclosing a set of <div>s (one for each column). The enclosing div is given a display: table attribute and each enclosed div is given a display: table-cell attribute.
