JS 实现中英文翻译

     缺点就是还是会闪出中文，但是效果还行。

    

    var langPackage = {
"主题":"Title",
    "下一页":"NextPage",
    "末页":"LastPage",
    "首页":" FirstPage ",
    "上一页":" PreviousPage ",
    "待办工作":"MyTasks",
    "中":"Middle",
    "每页":" EachPage ",
    "条":" Record ",
    "共":" Total ",
    "页":" Page ",
    "第":" Current ",
    "工作主题":" ProcTitle"
    };

执行遍历 DOM 的逻辑

    /* 
        主调函数
        在 Jquery的 .read方法里调用 ReplaceChildChs($(document));
        或者页面的最后调用
        ReplaceChildChs($(document));
    */
    function ReplaceChildChs(nodeObj){
        // if($("#hdfUseLang").val()=="CN")return;
        if (nodeObj.children().length > 0){
            nodeObj.children().each(function(){
               ReplaceChildChs($(this));
    //            if ($(this)[0].nodeName.toUpperCase() == "TD"){
                FindChsAndReplaceIt($(this));
    //            }
            });
        } else {
            FindChsAndReplaceIt(nodeObj);
        }

    // 直接替换html 的一种设想，但总是报错
