JS set the focus position in the text box at the end of the sample code (simple and practical) _javascript tips

In Firefox browser directly using This.focus (), you can achieve.

In IE, after This.focus (), the value of the text box is assigned to the text box, and the focus is at the end. Very simple Yo!!

Such as:

Copy Code code as follows:

var tar=document.getelementbyidx_x ("name");
if (tar.attachevent) {
Tar.attachevent (' onmouseover ', focus (TAR), false);
}else{
Tar.addeventlistener (' MouseOver ', focus (TAR), false);
}
function focus (TAR) {

Tar.focus ();
Tar.value=tar.value;
}
