The execution relationship between the HTML hyperlink a tag’s jump and onclick
The “a” tag of HTML is used to jump. However, if the onclick event is added, the execution order?
As follows:
[code]
< a http: / / 1. HTML “onclick =” return confirm (‘Do you want to delete this node? ‘);” ><img src=” shanchu.gif “></a>

If onclick returns false, a does not jump;
If onclick returns true, a jumps

Note: add the return keyword in onclick

This is often used to judge before jumping!!
