从javascript提交虚拟表单后显示相同的页面

Question

我有这个javascript函数

function SaveData(index) {

    var myVirtualForm = document.createElement("form");
    myVirtualForm.setAttribute('method', "post");
    var name = $("#" + index + " a").attr('name');
    var url = "http://localhost/my_Project/communicator.php?command=save&id=" + name;
    myVirtualForm.setAttribute('action', url);

    var iframe = document.getElementById(index + "frame");
    var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
    var oTable = innerDoc.getElementById("reporttable");
    //alert(oTable.rows.item(0).cells.item(0).innerText);
    //gets table
    var str = "";
    var rowLength = oTable.rows.length;
    //gets rows of table
    for (i = 0; i < rowLength; i++) {
        //loops through rows

        var oCells = oTable.rows.item(i).cells;
        var cellLength = oCells.length;
        for (var j = 0; j < cellLength; j++) {
            var cellVal = oCells.item(j).innerText;
            var a = "";
            var b = a.concat(i.toString(), "_", j.toString());
            var obj = document.createElement("input");
            obj.setAttribute('type', "text");
            obj.setAttribute('name', b);
            obj.setAttribute('value', cellVal.toString())
            myVirtualForm.appendChild(obj);
        }
    }
    myVirtualForm.submit();
}

提交后我们去了communicator.php，但我想留在同一页面，谁不会改变。
