js冒泡法和数组转换成字符串

js代码:

window.onload = function(){

	var mian = document.getElementById( "mian" );

	var mian1 = document.getElementById( "mian1" );

	var str = mian.innerHTML;

	var arry = [];

	var len = str.length;

	for( var i = 0; i < len; i++ ){

		arry[ i ] =  str[ i ];

	};

	function paix1( arry ){

		var temp;

		while( len > 0 ){

			for( var j = 0; j < len - 1; j++ ){

				if( arry[ j ] > arry[ j+1 ] ){

					temp = arry[ j ];

					arry[ j ] = arry[ j + 1 ];

					arry[ j + 1 ] = temp;

				};

			};

			len--;

		};

		return arry;

	};

	mian1.innerHTML = paix1(arry).join("");           // 把数组转换成为字符串

};

html代码：

<div id="mian">vdwsxdfrthspas</div>

<div id="mian1"></div>
