I have an array of objects, say the object looks like following:
var row = {
data: 'test',
text: 'test'
};
I want to loop through the array and just get the object with text property.
What is the best way to do it?
So, I want to loop and the object should look like: row = {text: 'test'}
I tried something like below without luck:
arr.forEach(function (item){ //arr is the array of object
return {text: item.text};
});
Use Array.prototype.map for that:
var arr = [{
data: 'testData',
text: 'testText'
}];
var newArr = arr.map(function(item){
return {text: item.data};
});
The result will look like:
[{ text: 'testData' }]
If you want it to be [ {testText: 'testData' }] then:
var arr = [{
data: 'testData',
text: 'testText'
}];
var newArr = arr.map(function(item){
var obj = {};
obj[item.text] = item.data;
return obj;
});
As you want a object with single key value pair, you don't need to store in object form. You can save them as an array.
var array = [
{
text : "text",
data : "data"
},
{
text : "text1",
data : "data1"
}
]
var newArray = array.map(function(item){
return item.data;
});
your output will look like
['text','text1']
