each遍曆jquery對象<script type="text/javascript" > function readmessage(){ $("li").each(function(k,v){ console.log(k+‘----------‘+v); v.style.color="red"; //$(v).css(‘background‘,‘lightblue‘); }); } </script> </head> <body> <ul> <li>巴西</li> <li>德國</li> <li>法國</li> <li>英格蘭</li> </ul> <input type="button" value="觸發" onclick="readmessage()"/>//遍曆節點function f1(){ //遍曆節點 //$("li").css("color","red"); //通過each方法，給li賦予不同顏色 //jquery.fn 的方法each() 行數：279 $("li").each(function(){ //三個li的文字顏色都不一樣 //this 分別代表具體li的dom節點對象 //$(this) 把dom對象轉化為jquery對象 var rand1 = Math.floor(Math.random()*255); var rand2 = Math.floor(Math.random()*255); var rand3 = Math.floor(Math.random()*255); $(this).css("color","rgb("+rand1+","+rand2+","+rand3+")"); //this表示$("i") 代表調用each的這個jq對象。 });}由以上兩種方式可以得出：this對象也就是DOM對象v也是dom對象
