動態定位到頁面上任一控件代碼

這個可以在onclick時定位到當前控件的底下（減去了左移滾動條）function show(tt) 。

 

<script language="javascript">
        var outobj=null;
        function show(tt) {
            outobj = tt;
            var th = tt;
            var ttop = tt.offsetTop;
            var thei = tt.clientHeight;
            var tleft = tt.offsetLeft;
            var ttyp = tt.type;
           
            while (tt = tt.offsetParent) { ttop += tt.offsetTop; tleft += tt.offsetLeft; if (tt.scrollLeft > 0) tleft -= tt.scrollLeft; }
           
            document.all.sss.style.top = (ttyp == "image") ? ttop + thei : ttop + thei + 6;
            document.all.sss.style.left = tleft;
        }
        function setval(val) {
            if (outobj == null) return;
            outobj.value = val.value;
            document.all.sss.style.top = 9;
            document.all.sss.style.left = 9;
            outobj = null;
        }

//點外面時隱掉
        function document.onmouseup() {
            with (window.event) {
                if (srcElement != outobj && srcElement.getAttribute("setvals") == null) {
                    document.all.sss.style.top =9;
                    document.all.sss.style.left = 9;
                    outobj = null;
                }              
            }
            window.event.srcElement.click();          
        }
    </script>
