小编use*_*474的帖子

我没有收到来自服务器的JSON类型数据的响应.

我正在使用JSON插件.

jQuery( "#dialog-form" ).dialog({ 
    autoOpen: false,
    height: 500,
    width: 750,
    modal: true,
    buttons :{
        "Search" : function(){
            jQuery.ajax({type : 'POST',
            dataType : 'json',
             url : '<s:url action="part" method="finder" />',
         success : handledata})
        }
    }
});
var handledata = function(data)
{
    alert(data);
}

如果dataType = 'json'我没有得到任何回复,但如果我没有提及任何回复,dataType我将获得该页面的HTML格式.

public String list(){
    JSONObject jo = new JSONObject();
    try {
        Iterator it = findList.iterator();
        while(it.hasNext()){
             SearchResult part = (SearchResult) it.next();
             jo.put("col1",part.getcol1());
             jo.put("col2",part.getcol2());
        }
        log.debug("--------->:"+jo.toString());
    } catch (Exception e) {
        log.error(e); …

打开窗体时,光标在文本框中等待帮助文本.因此,发生了一些验证错误.因此我不想在打开表单时使用焦点,用户必须单击文本并键入文本.但是文本框中的光标没有任何onfocus事件.

if(!$.trim($("#productsTextArea1").val())){
        helpTip = "help string ....";
        $("#productsTextArea1").val(helpTip);
        $("#productsTextArea1").css("color","#999");
        $("#productsTextArea1").click(function(event){
            if($("#productsTextArea1").val().indexOf("Enter a return")>-1){
                $("#productsTextArea1").css("color","black").val("");
            }
        });
    } else {
         $("#productsTextArea1").blur();
    }

请指教...

的jsfiddle

我试图单独更改为标题栏颜色.所以我使用了.ui-dialog-titlebar,但它不起作用,所以我尝试使用ui-widght-header,它反映到数据表也..请指教.

//不工作

.ui-dialog-titlebar {
  background-color: #F9A7AE;
  background-image: none;
  color: #000;
}

//工作,但反映到数据表头也..

.ui-widget-header
{
    background-color: #99CCFF;
    background-image: none;
    color: Black;
}

我正在寻找只有颜色的对话框标题栏.请指教.

如何突出显示数据表中的选定行.我在jsfiddle中用jquery代码数据表更新了html.请帮我写css以突出显示不同颜色的选定行.

var oTable = $("#products1").dataTable({
       "aaData": newarray,
       "bProcessing": true,
       "bDeferRender": true,
       "bFilter": false,
       "bJQueryUI": true,
       "bRetrieve": true,
       "bPaginate": false,
       "bSort": true,
       "aaSorting": [[4, "desc"]],
       "iDisplayLength": 25,
       "aoColumns": [{"sWidth": "100%","sClass": "center","bSortable": false},
             {
            "sWidth": "150%","sClass": "center","bSortable": false},
             {
            "sWidth": "150%","sClass": "center","bSortable": false},
             {
            "sWidth": "150%","sClass": "center","bSortable": false}


            ],
        "aoColumnDefs": [{ "fnRender": function (o, val) {
            return o.aData[0];
        },
            "sClass": "col1","aTargets": [0]
    }, {
        "fnRender": function (o, val) {

            return o.aData[1];
        },
            "sClass": "col2","aTargets": [1]
    }, {
    "fnRender": function (o, val) { …

我有方法将返回将显示为文本字符串的值.所以我正在做的是转换为ByteArrayInputStream.

public String method() {
    inputStream = new ByteArrayInputStream(prod().getBytes());
    return method;
}

prod()是一种返回值的方法.它给了我一个错误ByteArrayInputStream cannot be resolved to a type.请指教.

我在datatable中实现了excel导出.已将tabletool引用和SWF放入我的本地工作区.

var oTable = $("#products").dataTable({
       "aaData": newarray,
       "bProcessing": true,
       "bDeferRender": true,
       "bFilter": false,
       "bRetrieve": true,
       "bPaginate": true,
       "bJQueryUI": true,
       "sPaginationType": "two_button",
       "sDom": '<"H"Tfr>t<"F"ip>',
       "oTableTools": {
            "sSwfPath": "../swf/copy_csv_xls.swf",
             "aButtons": [ "xls" ]
        },
       "bSort": true,

它只是在表头中显示导出选项,但没有动作,什么也没发生.我有什么步骤需要做吗？如果我在没有提及oTableTools的情况下保持空白,打印选项工作正常,所以我的环境运行良好.

请告知我没有做哪一步？

谢谢

我收到的电子邮件地址就像user.q@stackoverflow.com.我想在java中的电子邮件地址的'@'符号前添加字符串.

在电子邮件地址中添加字符串后:user.qzzz@stackoverflow.com.如何在java中的@符号前插入'zzz'字符串？

我在我的数据中有分页,我实现了选定的行突出显示功能...此功能(行突出显示)在第一页中有效,但第二页和第三页不起作用.

我已经更新了jsfiddle中的代码,请查看建议.

var oTable = $("#products").dataTable({
    "aaData": [
        ["one", "two", "three", "four"],
        ["five", "six", "seven","eight"],
        ["one", "two", "three", "four"],
        ["one", "two", "three", "four"],
        ["one", "two", "three", "four"],
        ["one", "two", "three", "four"],
        ["one", "two", "three", "four"]

    ],
        "bProcessing": true,
        "bDeferRender": true,
        "bFilter": false,
