Question

我在javascript中面临异步调用问题，错误（不是预期的）值传递给函数。见伪代码：

    i=0;
    while(i<10){  
        var obj= {something, i};    
        getcontent(obj); //( <--- getcontent is async function/problem)      
     i++;
    }

所有getcontent异步调用都使用最后一个i = 9值，这不是我想要实现的我应该如何处理这样的异步调用并在每次调用中获得正确/传递正确的值？

Answer 1

<script>
var i = 0;
while (i < 5) {
setTimeout(function() { 
 getcontent()
}, 2000);  
    i++;
}
function getcontent(){
alert()
}
</script>

希望它能帮到你

这个怎么样：

async function loop(){
    var i: number = 0;
    while (i < 10) {
        (async function () {
            var obj = { "@": "fd", "#": i };
            await getcontent(obj); //( <--- getcontent is async function/problem)      
            i++;
        })();
    }
}
