//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
另：前提是两个数组中的项没有重复，如果重复，将不能达到想要的效果
