alert弹出内容怎么让它不弹出而显示在网页中？

[tsh888]

<script type="text/javascript">

        function handleError(value) {
            switch (value.code) {
                case 1:
                     alert("测试1");
                    break;
                case 2:
                     alert("测试2");
                    break;
                case 3:
                    alert("测试3");
                    break;
                case 4:
                     alert("测试4");
                    break;
            }
        }
</script>

如何将上面的弹出内容用<div id="map" style="width:100%;height:300px;"></div>调用显示到网页中？谢谢！

[当作看不见]

function handleError(value) { switch (value.code) { case 1: map.innerHTML+="测试1"; alert("测试1"); break; case 2: map.innerHTML+="测试2"; break; case 3: map.innerHTML+="测试3"; break; case 4: map.innerHTML+="测试4"; break; } }

documnet.write("测试") 替换你的alert()方法

[forwardNow]

<div id="map" style="width:100%;height:300px;"></div>

<script type="text/javascript">
 
    function handleError(value) {
        var result
        ;
        result = "";

        switch (value.code) {
            case 1:
                alert("测试1");
                result = "测试1";
                break;
            case 2:
                result = "测试2";
                alert("测试2");
                break;
            case 3:
                result = "测试3";
                alert("测试3");
                break;
            case 4:
                result = "测试4";
                alert("测试4");
                break;
        }
        
        document.getElementById( "map" ).innerHTML = result;
    }
</script>

引用 3 楼 wuqinfei_cs 的回复:

<div id="map" style="width:100%;height:300px;"></div>

<script type="text/javascript">
 
    function handleError(value) {
        var result
        ;
        result = "";

        switch (value.code) {
            case 1:
                alert("测试1");
                result = "测试1";
                break;
            case 2:
                result = "测试2";
                alert("测试2");
                break;
            case 3:
                result = "测试3";
                alert("测试3");
                break;
            case 4:
                result = "测试4";
                alert("测试4");
                break;
        }
        
        document.getElementById( "map" ).innerHTML = result;
    }
</script>

非常感谢！
