jquery_自定義鼠標右鍵

一、自定義鼠標右鍵的實現(xiàn)原理

TIM圖片20180911164755.png

自定義右鍵菜單功能，需清楚，所有瀏覽器都自帶了右鍵功能，那么自定義右鍵菜單，需要先屏蔽系統(tǒng)自帶的右鍵功能，如何實現(xiàn)呢？

$selector.on('contextmenu', '.box', function () {

    return false;

})

注：$selector為選擇器，.box為禁用鼠標右鍵的class
完成系統(tǒng)自帶鼠標右鍵的禁用后，開始自定義鼠標右鍵。

獲取鼠標事件的方法，使用mousedown,獲取后需區(qū)分是鼠標左鍵還是右鍵，事件返回的參數(shù)event中，event.which為3表示右鍵，為1表示左鍵，為2表示中鍵。如下：

$("#box").mousedown(function(e){

      if(3 === e.which){

           alert("這 是右鍵單擊事件");

        }else if(1 === e.which){ 

               alert("這 是左鍵單擊事件");

         }  else if (2  ===  e.which)  {

            alert("這是鼠標中鍵");

        }

    })

二、自定義鼠標右鍵實例（表格行右鍵自定菜單）

html:

<div class="box">
<div class="table-list">
    <div class="table-thead ">
        <ul class="table-col">
            <li class="save-item" title="名稱">

            </li>
            <li class="save-item" title="類型">
                <span>類型</span>
            </li>
            <li class="save-item" title="數(shù)據(jù)">
                <span>數(shù)據(jù)</span>
            </li>
            <li class="save-item">
