我使用下面的语法来查找页面加载时间但不确定如何使用javascript识别页面呈现时间。
public static int[] get_merged_array(int[] a, int[] b, int a_size, int b_size)
{
int[] merged_array = new int[a_size + b_size];
int i = 0 , j = 0, x = -1;
for(; i < a_size && j < b_size;)
{
if(a[i] <= b[j])
{
merged_array[++x] = a[i];
++i;
}
else
{
if(merged_array[x] != b[j])
{
merged_array[++x] = b[j]; // avoid duplicates
}
++j;
}
}
--i; --j;
while(++i < a_size)
{
merged_array[++x] = a[i];
}
while(++j < b_size)
{
merged_array[++x] = b[j];
}
return merged_array;
}
