C - Getting user input for a char * in a struct

You first have to allocate memory to it. So do something like this:

for(i = 0; i < 10; i++) {
    route[i].startingLocation =
malloc(sizeof(char) * 1024);

Now you can use the adress in startingLocation to pass it like this:

scanf("%s", route[i].startingLocation) 

Be aware that you have to know beforehand how large the input will be (in this example it's 1 KB).

ajax validating input makes input unwritable or hardly writable

Then you need to return result from AJAX success function (not after it) but then your code will need to be deeply modified because if request will be asynchronous then your function will return before response will come.
