你好，帮你看了下，看是不是你要的结果
function compression(str){if(str.length == 0){
return 0
}
var len = str.length
var str2=""
var i=0
var num=1
while(i<len){
if(str.charAt(i)==str.charAt(i+1)){
num++
}else{
str2+=num
str2+=str.charAt(i)
num = 1
}
i++
}
return str2
}
先说明:a1,a2,a3,a4,a5,在返回的字符串中应该加",否则js会报错.除非在你的环境里,a1,...a5是已经定义的变量.
以下是使用代码.

//这里演示的是服务器返回的数据,字符串形式.这方法在回调函数中使用.在实例使用时,result应该替换为服务器返回的数据.
var resultjson = eval(result)
var div = document.getElementById("info")
for (var i = 0i <resultjson.lengthi++) {
div.innerHTML += resultjson[i].aa
if (i <resultjson.length - 1) {
div.innerHTML += ","
}
}
}
window.onload = handler

has no method 'submit' 是说jquery.easyui.min.js里面没得“submit“这个方法，是否是因为这个”submit“方法是在另外的js里面，而你没有引用。你把你的源码放出来吧。
