js合并数组

关键javascript代码：

//合并数组的函数
function mergeArray(arr1, arr2) {

    var arr = [];
    for ( i = 0; i < arr1.length; i++) {
        arr.push(arr1[i]);
    }
    var dup;
    for ( i = 0; i < arr1.length; i++){
        dup = false;
        for ( j = 0;j < arr2.length; j++){
            if (arr2[j] == arr1[i]){
                dup = true;
                break;
            }
        }
        if (!dup){
            arr.push(arr1[i]);
        }
    }
    return arr;

}

下面是一个示例

1.html 代码：

<html>
<head>
    <script type="text/javascript " src="binji.js " >

    </script>
</head>
<input type='button' value='show_result' onclick='test()'/>
</html>

2.javascript代码：

/**

 */

function test(){
    var arr1 = ["z1", "quiz2", "quiz3", "quiz4", "quiz5", "quiz6", "quiz7","2342343"];
    var arr2 = ["z1", "quiz2", "quiz3","gbds","ofwejf","9238ru23"];
    alert(mergeArray(arr1,arr2));

}
//合并数组的函数
function mergeArray(arr1, arr2) {

    var arr = [];
    for ( i = 0; i < arr1.length; i++) {
        arr.push(arr1[i]);
    }
    var dup;
    for ( i = 0; i < arr1.length; i++){
        dup = false;
        for ( j = 0;j < arr2.length; j++){
            if (arr2[j] == arr1[i]){
                dup = true;
                break;
            }
        }
        if (!dup){
            arr.push(arr1[i]);
        }
    }
    return arr;

}
