页面元素

定义一个测试菜单

1	<button type="button" id="test" class="btn btn-primary">鼠标右键测试</button>

js绑定事件

绑定元素右键点击事件。

$(document).ready(function() {
  $.contextMenu({
    selector: '#test', //右键选择器
    callback: function(key, options) {//点击回调处理
      var m = "clicked: " + key;
      window.console && console.log(m) || alert(m);
    },
    items: {//菜单列表配置
      "edit": {name: "Edit", icon: "edit"},
      "cut": {name: "Cut", icon: "cut"},
      copy: {name: "Copy", icon: "copy"},
      "paste": {name: "Paste", icon: "paste"},
      "delete": {name: "Delete", icon: "delete"},
      "sep1": "---------",
      "quit": {name: "Quit", icon: function(){
        return 'context-menu-icon context-menu-icon-quit';
    }}
    }
  });
});

js代码示例

$(document).ready(function() {
  $.contextMenu({
    selector: '#test', //右键选择器
    callback: function(key, options) {//点击回调处理
      var m = "clicked: " + key;
      window.console && console.log(m) || alert(m);
    },
    items: {//菜单列表配置
      "download": {name: "下载", icon: "fa-download"},
      "fa-lock": {name: "lock", icon: "fa-lock"}
    }
  });
});

禁用右键菜单

禁用右键菜单按钮，需要配置disabled:true

$(document).ready(function() {
  $.contextMenu({
    selector: '.btn', //右键选择器
    callback: function(key, options) {//点击回调处理
      var m = "clicked: " + key;
      window.console && console.log(m) || alert(m);
    },
    items: {//菜单列表配置
      "download": {name: "下载", icon: "fa-download",disabled: false},
      "fa-lock": {name: "lock", icon: "fa-lock",disabled: true}
    }
  });
});

动态禁用右键菜单

动态禁用可以通过function函数处理。

假如buttion中cutDisabled=”1” 代表禁用，那么具体实例代码如下：

html代码

1 2	<button type="button" class="btn btn-primary">鼠标右键测试1</button> <button type="button" cutDisabled="1" class="btn btn-primary">鼠标右键测试2</button>

js代码

$(document).ready(function() {
  $.contextMenu({
    selector: '.btn', //右键选择器
    callback: function(key, options) {//点击回调处理
      var m = "clicked: " + key;
      window.console && console.log(m) || alert(m);
    },
    items: {//菜单列表配置
      "download": {name: "下载", icon: "fa-download",disabled: false},
      "fa-lock": {name: "lock", icon: "fa-lock",disabled:function(key, opt) {
        //假如buttion中cutDisabled="1" 代表禁用
        return $(this).attr("cutDisabled") =="1";
      }
    }
  });
});
