everyone! I have an array of items and i want to return a number of how many values match a specific State in US. For example,this is a working code: https://jsfiddle.net/fkj3bq5g/
JS:
const arr = ["Texas","Austin","TX","Texas","San Antonio","TX","California","Los Angeles","CA"];
const results = arr.filter(elem => elem === "Texas").length;
document.getElementById("demo").innerHTML = results;
html:
<span>Texas Cities:</span><span id="demo"></span>
I''m trying to match "Texas" and it should return "2",which it does.
However,i encounter a problem as soon as i'm trying to put an array from of a .json file which have characters like { , } and : - i'm not getting any results. I'm not sure why,since i'm pretty much a noob anyway.
Here's an example how the array in the .json file looks like:
var state_city = [
{"state":"Texas","city":"Houston","code":"TX"},
{"state":"Texas","city":"Dallas","code":"TX"},
{"state":"Texas","city":"Austin","code":"TX"},
{"state":"California","city":"Los Angeles","code":"CA"},
{"state":"California","city":"Sacramento","code":"CA"},
{"state":"California","city":"Anaheim","code":"CA"},
]
How do i make this work?
