The difference between the href and the onclick JavaScript is generally useless to the attention, but the error is somewhat depressed, read this chapter explains the following:

Had always been very casual, later see. NET LinkButton seems to be used in <a href= "Javascript:fun ();" The form of ...>,
Today in this way encountered some problems, pick the Netizen's article and my conclusions placed below:

1. linked   onclick   event is executed first, followed by   href   Properties Action (page jump, or JavaScript
2. If   is present in the link, href   and   onclick , if you want to   href The action under the   property does not execute, onclick   must get a   false   return value. Do not believe, you can   gogoogle   function   return false   comment out;
3. if the page is too long with scroll bars, And you want to perform the action through the linked   onclick   event. It should be   href   property set to   javascript:void (0); , not   # , This prevents unnecessary page jumps;
4. if a function with a return value is called in the linked   href   property, the contents of the current page will be replaced by the return value of the function;
5. There is a difference when you hold down the SHIFT key.
6. The problem I encountered today, IE6.0 in the form of href access to parentnode.
7. Try not to use JavaScript: protocol as the HREF attribute of a, which not only leads to unnecessary triggering of window.onbeforeunload events, but also makes GIF animated pictures stop playing in IE.
