通过循环动态数组元素

Question

I am trying to create an array of images in javascript for my website when I declare array size it is working but when I am trying to take it as a dynamic array it is not showing images. can anyone tell me what's wrong with this code?

var theImages = new Array()
for (i = 0; i < theImages.length; i++) 
{  
  theImages[i] = i+".jpg"
}

Answer 1

The initial size of theImages is 0.

You need to use

for (i = 0; i < 5; i++) 
{  
  theImages[i] = i+".jpg";
}

replace 5 by the number of images you have.

Answer 2

This is happening because you are looping an empty array, the length/size of the array is 0 because you have just created a new array and are looping it without any elements in it yet.

If you wish to add all images to an array, you will have to know the total number of images you have/ count of images, and then run the loop to add the images in the array, which you were able to do successfully you said.

var theImages = new Array();
for (i = 0; i < 6; i++) 
{  
theImages[i] = i+".jpg";
}

If you are getting the image names for SQL, it is a different query you want to use, let me know if that is what you are looking for.
