Javascript disables the selected text implementation code of the document element Object

Copy codeThe Code is as follows: // The obj parameter: The jquery object of the element of the selected text to be disabled
// Parameter enabled: true, optional; false, not selected
Function setSelectable (obj, enabled ){
If (enabled ){
Obj. removeAttr ("unselectable "). removeAttr ("onselectstart" ).css ("-moz-user-select", "" ).css ("-webkit-user-select ","");
} Else {
Obj. attr ("unselectable", "on "). attr ("onselectstart", "return false;" ).css ("-moz-user-select", "none" ).css ("-webkit-user-select ", "none ");
}
}

The principle is as follows::

In ie, you can disable the selected text by setting the processing function (return false;) of the event selectstart.
In ff and chrome, css can be used to control
As for the unselectable attribute, it can be seen as a complementary means to adapt to more browsers as much as possible.
