仅IE不支持setTimeout/setInterval函数的第三个以上参数-javascr

setTimeout(function(obj){
alert(obj.a);
}, 2000, {a:1});

setTimeout(function(obj){
obj.method();
}, 2000, obj);

setTimeout(function(a, b){
alert(a);
alert(b);
}, 2000, 1,2);

setTimeout(function(){
alert(arguments.length);
}, 2000, 1,2);

//解决IE下setTimeout传参数的bug
if(!+[1,]) {
(function(overrideFun){
window.setTimeout = overrideFun(window.setTimeout);
window.setInterval = overrideFun(window.setInterval);
})(
function(originalFun){
return function(code, delay){
var args = [].slice.call(arguments, 2);
return originalFun(
function(){
if (typeof code == 'string') {
eval(code);
}
else {
code.apply(this, args);
}
},
delay
)
}
}
);
}
