Question

我想将all_dragable_obj_left和all_dragable_obj_top数组传递给dragGo函数：

1。 document.attachEvent("onmousemove", dragGo);和

2。 document.addEventListener("mousemove", dragGo, true);。

以下是代码：

function dragStart(event, id) {
    var el;
    var x, y;

    if (id)
        dragObj.elNode = document.getElementById(id);
    else {
        if (browser.isIE)
            dragObj.elNode = window.event.srcElement;
        if (browser.isNS)
            dragObj.elNode = event.target;

        if (dragObj.elNode.nodeType == 3)
            dragObj.elNode = dragObj.elNode.parentNode;
    }

    if (browser.isIE) {
        x = window.event.clientX + document.documentElement.scrollLeft + document.body.scrollLeft;
        y = window.event.clientY + document.documentElement.scrollTop + document.body.scrollTop;
    }
    if (browser.isNS) {
        x = event.clientX + window.scrollX;
        y = event.clientY + window.scrollY;
    }

    // Save starting positions of cursor and element.
    $("img[class=obj_mov]").each(function () {                
        all_dragable_obj_left.push(parseInt($(this).css("left"), 10));
        all_dragable_obj_top.push(parseInt($(this).css("top"), 10));
    });
    dragObj.cursorStartX = x;
    dragObj.cursorStartY = y;
    if (browser.isIE) {
        document.attachEvent("onmousemove", dragGo);
        document.attachEvent("onmouseup", dragStop);
        window.event.cancelBubble = true;
        window.event.returnValue = false;
    }
    if (browser.isNS) {
        document.addEventListener("mousemove", dragGo, true);
        document.addEventListener("mouseup", dragStop, true);
        event.preventDefault();
    }
}

function dragGo(event) {
    var x, y;
    if (browser.isIE) {
        x = window.event.clientX + document.documentElement.scrollLeft + document.body.scrollLeft;
        y = window.event.clientY + document.documentElement.scrollTop + document.body.scrollTop;
    }
    if (browser.isNS) {
        x = event.clientX + window.scrollX;
        y = event.clientY + window.scrollY;
    }
    var i = 0;
    i = 0;
    $("img[class=obj_mov]").each(function () {
        $(this).css("left",all_dragable_obj_left[i]+ x - dragObj.cursorStartX);
        $(this).css("top",all_dragable_obj_top[i]+ y - dragObj.cursorStartY);
        i++;
    });            

    if (browser.isIE) {
        window.event.cancelBubble = true;
        window.event.returnValue = false;
    }
    if (browser.isNS)
        event.preventDefault();
}

function dragStop(event) {
    dragObj.elNode = null;
    if (browser.isIE) {
        document.detachEvent("onmousemove", dragGo);
        document.detachEvent("onmouseup", dragStop);
    }
    if (browser.isNS) {
        document.removeEventListener("mousemove", dragGo, true);
        document.removeEventListener("mouseup", dragStop, true);
    }
}

Answer 1

1。第一

document.attachEvent("onmousemove", function(e){
    dragGo(e, all_dragable_obj_left, all_dragable_obj_top);
});

2。第二

document.addEventListener("mousemove", function(e){
    dragGo(e, all_dragable_obj_left, all_dragable_obj_top);
}, true);

3。 dargGo()功能

function dragGo(event, all_dragable_obj_left, all_dragable_obj_top) {

    var x, y;
    if (browser.isIE) {
        x = window.event.clientX + document.documentElement.scrollLeft + document.body.scrollLeft;
        y = window.event.clientY + document.documentElement.scrollTop + document.body.scrollTop;
    }
    if (browser.isNS) {
        x = event.clientX + window.scrollX;
        y = event.clientY + window.scrollY;
    }
    var i = 0;
    i = 0;
    $("img[class=obj_mov]").each(function () {
        $(this).css("left",all_dragable_obj_left[i]+ x - dragObj.cursorStartX);
        $(this).css("top",all_dragable_obj_top[i]+ y - dragObj.cursorStartY);
        i++;
    });            

    if (browser.isIE) {
        window.event.cancelBubble = true;
        window.event.returnValue = false;
    }
    if (browser.isNS)
        event.preventDefault();
}

将两个数组发送到使用document.attachEvent运行的函数（“onmousemove”，dragGo）
