I am getting json response from service i wanted to get region_name property value from first block only. Following is my json object.
[
{
"blogid": 286,
"post_title": "Family Time 2",
"post_content": "",
"post_date": "2017-07-27 06:26:34",
"imageurl": "/wp-content/Love-market-banner.jpg",
"region_name": "Asia",
"cat_name": [
{
"term_id": 9,
"name": "FAMILY TIME",
"slug": "family-time",
"category_description": "this is family time",
"cat_name": "FAMILY TIME",
"category_nicename": "family-time",
"category_parent": 0
}
]
},
{
"blogid": 285,
"post_title": "Family Time 1",
"post_content": "",
"post_date": "2017-07-27 06:26:09",
"imageurl": "/wp-content/reykjavik-xlarge.jpg",
"region_name": "Asia",
"cat_name": [
{
"term_id": 9,
"name": "FAMILY TIME",
"slug": "family-time",
"category_description": "this is family time",
"cat_name": "FAMILY TIME",
"category_nicename": "family-time",
"category_parent": 0
}
]
}
]
My typescript code is as follows
Blogbyregion(regid: any)
{
var self = this;
self.blogapi.BlogsbyRegion(regid).subscribe(
x => {
this.Blogbyreg = x;
});
}
and in html i have used
{{Blogbyreg[0]?.region_name}}
I am getting result but also getting error
ERROR TypeError: Cannot read property '0' of null
You should either initialize your Blogbyreg field like Blogbyreg = [] or do a null check for it.
