页面上拼写列表时 onclick="",左斜线表示转意，告诉程序这是双引号

td += "<tr><td><input type='checkbox' name='siteChoice' id='siteChoice"+newKey+"' onclick='changeCheck(this)' value='"+key+"'/><span id='choice"+newKey+"'>"+(j+1)+"</span></td>"+
"<td>"+terminalName+"</td>"+
"<td>"+unitName+"</td>"+
"<td ><input type='hidden' id='siteStatus"+newKey+"' value='"+siteStatus+"'/><a class='"+siteStatusClassName+"' href='javascript:void(0);' id='siteStatusButton"+newKey+"' onclick="changeThisSiteStatus('"+newKey+"')"></a></td>"+
"<td><input type='hidden' id='isQuiet"+newKey+"' value='"+isQuiet+"'/><a class='"+quietClassName+"' href='javascript:void(0);' id='isQuietButton"+newKey+"' onclick="changeThisSiteQuiet('"+newKey+"')"></a></td>"+
"<td ><input type='hidden' id='isMute"+newKey+"' value='"+isMute+"'/><a class='"+muteClassName+"' href='javascript:void(0);' id='isMuteButton"+newKey+"' onclick="changeThisSiteMute('"+newKey+"')"></a></td>"+
"<td><div class='dragItem'>"+key+"</div></td>"+
"<td><input type='text' value='0' id='vol"+newKey+"' onkeyup='replayStr(this)' onafterpaste='replayStr(this)' style='30px'><a href='javascript:void(0)' onclick="changeVolume('"+newKey+"')">设置</a></td>"+
"<td><a href='javascript:void(0)' onclick="moveUp('"+newKey+"')">向上</a>"+
"<a href='javascript:void(0)' onclick="moveDown('"+newKey+"')">向下</a></td>"+
"</tr>";

问题：<a href='javascript:void(0)' onclick='moveUp("+newKey+")'>向上</a>

原因是该参数必须要用单引号

  以上是用调试工具看newKey参数值为02720 类型为String

  而在js function moveUp(uri){

      alert(uri)//uri为1488 类型为number

}
