@Taplar that's far too complicated for this question... something like this is more appropriate in my opinion: https://stackoverflow.com/questions/8238456/how-to-get-value-at-a-specific-index-of-array-in-javascript — GrafiCode, Feb 17 '20 at 17:52

You can simply access a value in your array available_dates by doing this:

document.getElementById('app_date').value = available_dates[i]

Be careful to the fact that indexes start from 0. so available_dates[0] will return the first index. available_dates[1] will return the second and so on.

U must indicate which position of the array u want:

document.getElementById('app_date').value = available_dates[1]

Simply access array by its key available_dates[1]

function getDate() {
  var available_dates = ["08-11-2018","09-11-2018"]  
  document.getElementById("myText").value = available_dates[1];
}

<input type="text" id="myText" value="">

<button onclick="getDate()">Get Date</button>

Thanks ....but what if var available_dates was in another script not in the same function , how to detecte the value !! – ADDA BENDADI Feb 17 '20 at 18:52
hi see in any language if you want to access a variable it should be declared before it's use so if the variable is in another script file than include that file before this function is being called and than use that variable – Passionate Coder Feb 18 '20 at 04:37
