在我目前的春季项目中，我有这样的结构：一个仪表板页面，我有一个菜单，其中包含指向我的应用程序中所有子页面的链接。每个链接都在<div>内打开，显示在jquery-ui对话框中。

dashboard.jsp：

<%@ include file="../include/header.jsp" %>

    <div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="#">Project name</a>
        </div>
        <div class="collapse navbar-collapse">
          <ul class="nav navbar-nav">
            <li> <c:url value="/Usuario/listagem" var="usuario"/> <a href="#" class="popup" data-action="${usuario}/1/10/1" data-target="popup-usuario">Usu&aacute;rios</a></li>
            <li> <c:url value="/Permissao/listagem" var="permissao"/> <a href="#" class="popup" data-action="${permissao}/1/10/1" data-target="popup-permissao">Permiss&otilde;es</a></li>
            <li> <c:url value="/Grupo/listagem" var="grupo"/> <a href="#" class="popup" data-action="${grupo}/1/10/1" data-target="popup-grupo">Grupos</a></li>
            <li> <c:url value="/logout" var="logoutUrl"/> <a href="${logoutUrl}">Logout</a></li>
          </ul>
        </div><!--/.nav-collapse -->
      </div>
    </div>

    <div class="dialog" id="popup-usuario">
            <div id="text"> </div>
    </div>

    <div class="dialog" id="popup-permissao">
            <div id="text"> </div>
    </div>

    <div class="dialog" id="popup-grupo">
            <div id="text"> </div>
    </div>

<%@ include file="../include/footer.jsp" %>

正如我在上面的页面所做的那样，所有页面都有外部文件中的页眉和页脚，它们是：

标题 

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%@ page session="false" language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

<body>

页脚

</body>
</html>

我的控制器映射的每个视图都将客户端发送到类似于此的jsp页面：

<jsp:include page="../../common/listagem.jsp">
    <jsp:param name="name" value="Usuario"/>

    <jsp:param name="elements" value="login"/>
    <jsp:param name="elements" value="pnome"/>
    <jsp:param name="elements" value="unome"/>
    <jsp:param name="elements" value="email"/>

    <jsp:param name="label" value="Login"/>
    <jsp:param name="label" value="Nome"/>
    <jsp:param name="label" value="Sobrenome"/>
    <jsp:param name="label" value="E-mail"/>
</jsp:include>

common / listagem.jsp就是这样的：

<%@ include file="../include/header.jsp" %>

<c:url value="/${param.name}/cadastra" var="cadastra"/>
<c:url value="/${param.name}/altera" var="altera"/>
<c:url value="/${param.name}/remove" var="remove"/>

<input type="hidden" name="pagina" value="${pagina}">
<input type="hidden" name="items" value="${items}">
<input type="hidden" name="ordem" value="${ordem}">

<sec:authorize access="hasPermission(#user, 'cadastra_${param.name}')">
<p>
    <button type="button" class="btn btn-sm btn-link action" data-action="${cadastra}" data-target="cadastro">Cadastrar ${param.name}</button>
</p>
</sec:authorize>

<!-- Nav tabs -->
<ul class="nav nav-tabs">
  <li class="active"><a href="#listagem" data-toggle="tab">Listagem</a></li>

  <sec:authorize access="hasPermission(#user, 'cadastra_${param.name}')">

我的问题：

当我运行应用程序并打开每个子页面时，第一次一切都很好（除了表格只显示一个项目，什么时候应该全部显示）。如果我关闭页面，所有其他时间我打开它，表格显示重复的列。

任何人都可以看到这里有什么问题？

ps：从仪表板处理链接中的点击的JS代码是：

$( ".dialog" ).dialog({
      autoOpen: false,
      closeOnEscape: true,
      closeText: "fechar",
      show: {
        effect: "fadeIn",
        duration: 1000
      },
      hide: {
        effect: "fadeOut",
        duration: 1000
      },
      close: function( event, ui ) {
          $(this).remove();
      }
});
function add_dialog(container_div) {
    var id_dialog_div = Math.floor(Math.random() * 1000000);
    var dialog_div = $('<div id="dialog-'+id_dialog_div+'" class="dialog" title="Basic dialog"> <p> <span id="text'+id_dialog_div+'"></span> </p> </div>');
    $(container_div).append(dialog_div);
    return id_dialog_div;
}

function open_dialog(url, dialog_div) {
    $.ajax({
        type: "GET",
        url: url
    }).done(function(data){
        var id_dialog_div = add_dialog(dialog_div);
        var dialog_box = $('#dialog-'+id_dialog_div);

        var $temp  = $('<div/>', {html:data});

        $( dialog_box ).dialog( { title: $temp.find('title').text() } );
        $( dialog_box ).find('#text'+id_dialog_div).empty();
        $( dialog_box ).find('#text'+id_dialog_div).html( $temp.remove('head').html() );
        $( dialog_box ).dialog( { height: 680 } );
        $( dialog_box ).dialog( { width: 1046 } );
        $( dialog_box ).dialog( "open" );
    });
}
$(document).on('click', '.popup', function (event) {
    event.preventDefault();
    var action = $(this).data('action');
    var target = $(this).data('target');
    var div = $("#"+target);
    open_dialog(action, div);
});

用于动态生成表的代码是：

function load_content(lista, target) {
    var atributos = [];

    $(".col").each(function(){
        var property = $(this).data('property');
        atributos.push(property);
    });

    var pagina = $('input[name=pagina]').val();
    var items = $('input[name=items]').val();
    var ordem = $('input[name=ordem]').val();

    var url = lista;
    $.ajax({
        type: 'GET',
        url: url,
        data: {pagina: pagina, items: items, ordem: ordem}
    }).done(function(data){
        var json = jQuery.parseJSON( data );
        $.each(json.item, function(index, item){
            target.find("tbody.content").empty();

            var row = $('<tr id='+item.id+'>');
            var counter = 0;

            for(var i=0; i<atributos.length; i++) {
                if(atributos[i] == '#') {
                    row.append('<td></td>');
                }
                else if(atributos[i] == '') {
                    var col = $('<td>');
                    $(".comando").each(function(){
                        var nome = $(this).data("nome");
                        var action = $(this).data("action");
                        col.append('<button type="button" class="btn btn-sm btn-primary action" data-target="'+nome+'" data-action="'+action+'/'+item.id+'">'+nome+'</button>');
                    });
                    row.append(col);
                }
                else {
                    var token = item[atributos[i]];
                    row.append('<td>'+token+'</td>');
                }
            }

            target.find("tbody.content").append(row);
            target.find("tfoot").hide();
            counter++;
        });
    });
}

1 个答案:

答案 0 :(得分：0)

然后我终于解决了本主题中提出的问题。页面中只显示一个项目的部分，我解决了从块target.find("tbody.content").empty();中替换行$.each(json.item, function(index, item)的问题。对于列的重复，我想这是通过函数open_dialog中的一些改动来解决的，现在代码是这样的：

function open_dialog(url, dialog_box) {
    $.ajax({
        type: "GET",
        url: url
    }).done(function(data){
        var $temp  = $('<div/>', {html:data});

        $(dialog_box).find('.text').empty();
        $(dialog_box).find('.text').html( $temp.remove('head').html() );
        $(dialog_box).dialog( { title: $temp.find('title').text() } );
        $(dialog_box).dialog( "open" );
    });
}

并且在dashboard.jsp中，与对话框相关的块<div>是：

<div class="dialog" id="popup">
        <div class="text"> </div>
</div>
