After the page is loaded, specify the text box to get the focus and hover the cursor.

This is not a difficult technique. It is mainly for some server-side controls added to the page, especially Ajax controls, some controls may not have been initialized during document ready, the focus is invalid.

I made a stupid solution, applicable to the above situations:

$ (Function () {var curintervalid = setinterval (function () {If (document. activeelement. ID! = "<% = Txtorderid. clientid %> ") {$ (" # <% = txtorderid. clientid %> "). focus (); clearinterval (curintervalid) ;}, 100 );});

The principle is to check whether the target element has appeared every 100 milliseconds. If it appears, focus on it and stop the loop.

After the page is loaded, specify the text box to get the focus and hover the cursor.
