本文实例讲述了JS实现合并两个数组并去除重复项只留一个的方法。分享给大家供大家参考，具体如下：
rush:js;">
//It's merge arr1 and arr2,delete the same element only leave one
//It's only apdapter array. If object,no.
//The sequence of the two array is not required.
mergeArray:function (arr1,arr2){
for (var i = 0 ; i < arr1.length ; i ++ ){
for(var j = 0 ; j < arr2.length ; j ++ ){
if (arr1[i] === arr2[j]){
arr1.splice(i,1); //利用splice函数删除元素，从第i个位置，截取长度为1的元素
}
}
}
//alert(arr1.length)
for(var i = 0; i
效果
希望本文所述对大家JavaScript程序设计有所帮助。
