我这里有个这样的树形对象
var i1={
id:1,
name:1,
Is:[{
id:2,
name:2
},{
id:3,
name:3,
Is:[{
id:4,
name:4,
Is:[{
id:6,
name:6
},{
id:7,
name:7
}]
},{
id:5,
name:5,
Is:[{
id:8,
name:8
},{
id:9,
name:9
}]
}]
}]
}我现在想有一个函数，使得他可以输出一个HTML的表格，这样会不会很难？
var i1={
id:1,
name:1,
Is:[{
id:2,
name:2
},{
id:3,
name:3,
Is:[{
id:4,
name:4,
Is:[{
id:6,
name:6
},{
id:7,
name:7
}]
},{
id:5,
name:5,
Is:[{
id:8,
name:8
},{
id:9,
name:9
}]
}]
}]

};
function fn(data , deep){
var split = '';
for(var i = 0 ; i < deep ; ++i){
split+=' ';
}
split+='|-';
console.log(split+data.name);
if(typeof data.Is!='undefined'){
for(var i in data.Is){
fn(data.Is[i] , deep+1);
}
}
}
fn(i1,0);
效果图打开google浏览器，切换到Console选项卡，看下是不是你要效果。

rt.push("</div>");

}
return rt.join('');
}
$('#tree').html(buildtree(data));</script>
</body>
</html>已解决
var table=document.createElement("table");
var tr1=document.createElement("tr");
var tr2=document.createElement("tr");
for(var i in x){
if(i=="id"){
var td=document.createElement("td");
td.innerHTML=x[i];
tr1.appendChild(td);
}else if(i=="Is"){
var td=document.createElement("td");
creates(x[i],td);
tr2.appendChild(td);
}
}
table.appendChild(tr1);
table.appendChild(tr2);
document.body.appendChild(table);
}
function creates(x,d){
var table=document.createElement("table");
var tr1=document.createElement("tr");
var tr2=document.createElement("tr");
for(var i=0;i<x.length;i++){
for(var j in x[i]){
if(j=="id"){
var td=document.createElement("td");
td.innerHTML=x[i][j];
tr1.appendChild(td);
}else if(j=="Is"){
var td=document.createElement("td");
creates(x[i][j],td);
tr2.appendChild(td);
}
}
}
table.appendChild(tr1);
table.appendChild(tr2);
d.appendChild(table);
}
window.onload=function(){
create(i1);
}
id为2的没有子对象 所以导致往左漂了 回去看看 先留下bug的代码
