急!各位大哥,帮我看一下呀...

//相关函数如下
x=5;
function fun1(){
x=x-1;
.....;//语句组
if (x>=0){
setTimeout("fun1()",5);
}
}

function fun2(){
x=5;
}

function fun3(){
fun1();
fun2();
}
执行fun3的时候,想要让fun1执行完后再执行fun2.也就是说要让X=0时再执行fun2,该怎么做?

[zhaoweiwei]

function fun1(){
x=x-1;
.....;//语句组
if (x>=0){
setTimeout("fun1()",5);
}
else if(x=0){fun2}
}

[zhaoweiwei]

sorry


function fun1(){
x=x-1;
.....;//语句组
if (x>=0){
setTimeout("fun1()",5);
}
else if(x=0){fun2()}
}

function fun1(){
x=x-1;
.....;//语句组
if (x>=0)
setTimeout("fun1()",5);
else
fun2();
}

function fun3(){
fun1();
if(x=0)
fun2();
}
