AngularJS Question

AngularJS - Using indexOf inside ng-repeat to show/hide values

I have a

JSON
file that contains a bunch of data:

myData.JSON:

{
"Addresses": {
"AddressList": [
{
"HouseNumber": 201,
"Street": "Victoria Lane",
"Postcode": "SW1 8ES"
},
{
"HouseNumber": 10,
"Street": "Allen Close",
"Postcode": "NG2 3TD"
},
{
"HouseNumber": 57,
"Street": "Thomas Street",
"Postcode": "DR12 6TE"
},
{
"HouseNumber": 57,
"Street": "Old Lister Street",
"Postcode": "OL4 5TH"
},
{
"HouseNumber": 45,
"Street": "Milk Round Street",
"Postcode": "MK6 4HG"
},
{
"HouseNumber": 102,
"Street": "Jersey Quarter Avenue",
"Postcode": "DR12 6TE"
},
{
"HouseNumber": 845,
"Street": "MR HAPPY STREET",
"Postcode": "MR3 0FJ"
}
]
}


Im trying to show a
div
if a match on the returned value from Street is found via a indexOf

HTML:

<div ng-repeat="address in Addresses.AddressList">
{{ address.HouseNumber }}, {{ address.Street}}, {{ address.Postcode }}
<div ng-show="address.Street.toLowerCase().indexOf('MR HAPPY STREET') == 0">
MR HAPPY STREET WAS FOUND
</div>
<div ng-show="address.Street.toLowerCase().indexOf('Milk Round Street') == 0">
Milk Round Street WAS FOUND
</div>
</div>


This doesnt seem to work. Can you perform such
indexOf
via an
ng-show
?

Answer

Your problem is that you compare 2 strings which are not the same: after use toLowerCase() function your string Milk Round Street looks like milk round street. So indexOf() will return -1. That's why you need to compare 2 strings in lower case, such as:

<div ng-show="address.Street.toLowerCase().indexOf('mr happy street') == 0">

or:

<div ng-show="address.Street.toLowerCase().indexOf(('MR HAPPY STREET').toLowerCase()) == 0">
