How to find the value of the array object after push in Angular2
1
I have an array defined in angular2 .ts file as -
this.dropdownValue=;
And then i push values into them from different functions like -
this.dropdownValue.push({ item_text: this.organizationInfo.records[i]._fields[0].end.properties.name });
this.dropdownValue.push({ item_text: this.departmentInfo.records[i]._fields[0].end.properties.name });
The Console statements -
console.log("inside Proceed, this.dropdownValue =", typeof(this.dropdownValue));
console.log("inside Proceed, this.dropdownValue =", this.dropdownValue);
console.log("inside Proceed, this.dropdownValue =", this.dropdownValue[0]);
console.log("inside Proceed, this.dropdownValue =", this.dropdownValue.length);
There Outputs of a few values are -
typeOf(this.dropdownValue ) = object
this.dropdownValue =
[
0:{item_text: "IT"}
1:{item_text: "post"}
2:{item_text: "intimationDate"}
3:{item_text: "lossDescription"}
]
this.dropdownValue[0] = undefined
this.dropdownValue.length = 0
I want to access the values of -
item_text
.i.e store it in another variable/array.
And i am unable to do so.Neither am i able to access these values, no find its length nor find the value at a particular length

this.dropdownValue.find((elem) => elem.item_text === "IT")should work in case the texts are unique, developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

Hi Ashish, Thanks. this.dropdownValue[0] = undefined and this.dropdownValue.length = 0 are the outputs. And i don't wanna hardcode it. Like - you did --> === "IT". I want to place the entire item_text values into a variable
– Techdive
Nov 19 '18 at 17:44
If those are the outputs, then it seems you are accessing the array before it is populated? maybe outside some subscription, while the array under subscription. Is it getting populated throughsome async request?
– xyz
Nov 19 '18 at 17:49
And you want to store in a variable? How many variables will you make then? Another variable which is an array containg theitem_textwould be better in that case then

let otherVariable = this.dropdownValue.find(x => x.item_text === 'IT');
I edit my answer because I undestood right now what you are looking for.
let otherArray = ;
for (let obj of this.dropdownValue) {
otherArray.push(obj.item_text);
}
I know that is not the best way to do, but when i have to do something similar, i always do that
