我正在尝试动态创建所谓的portlet列表。可以通过单击按钮添加Portlet，该按钮打开包含3个输入字段的对话框，然后确认并在页面上显示新的portlet。这些portlet有一个减号图标，可用于切换portlet的文本部分。这适用于在页面加载时通过html添加的portlet，但动态添加的portlet似乎没有“绑定到它们”的此功能。
所以我想知道如何将这个功能添加到动态添加的portlet中。我也意识到我的jQuery代码看起来并不是最优的，但我主要是复制粘贴的东西，因为我是新手。
编辑：我应该添加以下链接：http://jqueryui.com/sortable/#portlets - 这是我从中获取大部分代码的地方，您可以测试减号图标功能。
jQuery的：
$(function() {
var title = $( "#title" ),
content = $( "#content" ), column = $( "#column" );
$( "#dialog-form" ).dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Add content": function() {
if(column.val()=='col1'){
$( "#col1" ).append($('<div class="portlet ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">' +
'<div class="portlet-header ui-widget-header ui-corner-all">' +
'<span class="ui-icon ui-icon-minusthick"></span>' + title.val() + '</div>' +
'<div class="portlet-content">' + content.val() + '</div></div>'))
$( this ).dialog( "close" );
}
else if(column.val()=='col2'){
$( "#col2" ).append($('<div class="portlet ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">' +
'<div class="portlet-header ui-widget-header ui-corner-all">' +
'<span class="ui-icon ui-icon-minusthick"></span>' + title.val() + '</div>' +
'<div class="portlet-content">' + content.val() + '</div></div>'))
$( this ).dialog( "close" );
}
else if(column.val()=='col3'){
$( "#col3" ).append($('<div class="portlet ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">' +
'<div class="portlet-header ui-widget-header ui-corner-all">' +
'<span class="ui-icon ui-icon-minusthick"></span>' + title.val() + '</div>' +
'<div class="portlet-content">' + content.val() + '</div></div>'))
$( this ).dialog( "close" );
}
else if(column.val()=='col4'){
$( "#col4" ).append($('<div class="portlet ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">' +
'<div class="portlet-header ui-widget-header ui-corner-all">' +
'<span class="ui-icon ui-icon-minusthick"></span>' + title.val() + '</div>' +
'<div class="portlet-content">' + content.val() + '</div></div>'))
$( this ).dialog( "close" );
}
else{
$( "#tempcol" ).append($('<div class="portlet ui-widget ui-widget-content ui-helper-clearfix ui-corner-all">' +
'<div class="portlet-header ui-widget-header ui-corner-all">' +
'<span class="ui-icon ui-icon-minusthick"></span>' + title.val() + '</div>' +
'<div class="portlet-content">' + content.val() + '</div></div>'))
$( this ).dialog( "close" );
}
},
Cancel: function() {
$( this ).dialog( "close" );
}
},
close: function() {
}
});
$( "#add-content" )
.button()
.click(function() {
$( "#dialog-form" ).dialog( "open" );
});
$( ".column" ).sortable({
connectWith: ".column"
});
$( ".portlet" ).addClass( "ui-widget ui-widget-content ui-helper-clearfix ui-corner-all" )
.find( ".portlet-header" )
.addClass( "ui-widget-header ui-corner-all" )
.prepend( "<span class='ui-icon ui-icon-minusthick'></span>")
.end()
.find( ".portlet-content" );
$( ".portlet-header .ui-icon" ).click(function() {
$( this ).toggleClass( "ui-icon-minusthick" ).toggleClass( "ui-icon-plusthick" );
$( this ).parents( ".portlet:first" ).find( ".portlet-content" ).toggle();
});
$( ".column" ).disableSelection();
});

答案 0 :(得分：1)
尝试使用动态元素
$("#centered").on('click', ".portlet-header .ui-icon", function(){...});
而不是
$( ".portlet-header .ui-icon" ).click(function(){...});
