单击jQuery UI小部件工厂中使用.on（）的事件

Question

我试图从jQuery UI选项卡实现simple manipulation功能。

但是我没有将代码放在窗口小部件之外，而是希望将它放在窗口小部件中。

“添加新标签”工作正常，但我在点击标签内关闭图标时遇到问题。我不确定如何使用小工厂处理该事件。

这是我迄今所做的：

JS：

$.widget("ui.tabs", $.ui.tabs, 
{ 
    _create: function(event, ui) 
    { 
     this._super(); 

     this._on($("span.ui-icon-close"), { 
     click: function() 
     { 
      var panelId = $(this).closest("li").remove().attr("aria-controls"); 
      $("#" + panelId).remove(); 
      this.refresh(); 
     }});  
    },  
    addTab: function(text, id) 
    { 
     var tab = "<li><a href='#" + id + "'>" + text + "</a><span class='ui-icon ui-icon-close' role='presentation'>Remove Tab</span></li>"; 
     var panel = "<div id='" + id + "'>This is new content! </div>"; 

     this.tabs.parent().append(tab); 
     this.panels.parent().append(panel); 

     this.refresh(); 
    }, 
}); 


$("#tabs").tabs(); 

$("#tabs").tabs("addTab", "New Tab", 3); 
$("#tabs").tabs("addTab", "Other Tab", 15);

Answer 1

如果你需要的是一个实际的点击事件，你可以执行你的魔法，那么这可以通过改变这条线来完成：

var tab = "<li><a href='#" + id + "'>" + text + "</a><span class='ui-icon ui-icon-close' role='presentation'>Remove Tab</span></li>"; 

to this：

var tab = $("<li>").html("<a href='#" + id + "'>" + text + "</a>"); 
var close = $("<span>") 
       .addClass("ui-icon ui-icon-close") 
       .attr("role","presentation") 
       .text("Remove Tab") 
       .on("click", function() { 
       // do whatever you want to do onclick 
       }); 
tab.append(close);

请试试这个。

$.widget("ui.tabs", $.ui.tabs, 
 
{ 
 

 
    _create: function(event, ui) 
 
    { 
 
     this._super(); 
 

 
\t \t this._on($("span.ui-icon-close"), { 
 
     click: function() 
 
     { 
 
     var panelId = $(this).closest("li").remove().attr("aria-controls"); 
 
     $("#" + panelId).remove(); 
 
     this.refresh(); 
 
     }});  
 
    },  
 
    addTab: function(text, id) 
 
    { 
 
     var tab = "<li><a href='#" + id + "'>" + text + "</a><span class='ui-icon ui-icon-close' role='presentation'>Remove Tab</span></li>"; 
 
     var panel = "<div id='" + id + "'>This is new content122121212! </div>"; 
 
     
 
     this.tabs.parent().append(tab); 
 
     this.panels.parent().append(panel); 
 
     
 
     this.refresh(); 
 
    }, 
 
    removeTab: function(eve) 
 
    { 
 
    $(eve).remove(); 
 
// Refresh the tabs widget 
 
\t \t $("#tabs").tabs("refresh"); 
 
    } 
 
}); 
 

 

 
$("#tabs").tabs(); 
 

 
$("#tabs").tabs("addTab", "New Tab", 3); 
 
$("#tabs").tabs("addTab", "Other Tab", 15); 
 

 
$(document).on('click', '.ui-icon-close', function (e) { 
 
    $("#tabs").tabs("removeTab", e.target.offsetParent); 
 
});

#tabs li .ui-icon-close { float: left; margin: 0.4em 0.2em 0 0; cursor: pointer; }
