I am having an json object below. I want to delete a part if the question value is empty. So according to below json I need to delete the id=7602 portion.
[ {
"id": 9333,
"component": "question_pool",
"sub_comp_arr": [
{
"id": 7769,
"component": "question",
"sub_comp_arr": [
{
"id": 2552,
"component": "question_segment",
"value": "Answer1"
},
{
"id": 1011,
"component": "question_segment",
"value": "Answer2"
},
{
"id": 8691,
"component": "question_segment",
"value": "Answer3"
}
],
"type": "single_choice",
"value": "<p>Question1?</p>\n"
},
{
"id": 7602,
"component": "question",
"sub_comp_arr": [
{
"id": 921,
"component": "question_segment",
"value": ""
}
],
"type": "single_choice",
"value": ""
}
]
},{...}
]
I have implemet the code as below
var y= content_json.content_arr;
var keyCount = Object.keys(y).length;
for (var i = 0; i < keyCount; i++) {
var questionCount = (content_json.content_arr[i]['sub_comp_arr']).length;
for (let j = 0; j < questionCount; j++){
var emptyquestion= ((content_json.content_arr[i]['sub_comp_arr'][j]['value']).trim()).length;
if (emptyquestion===0){
delete (content_json.content_arr[i]['sub_comp_arr'][j]);
}
}
}
But the problem is if I use delete (content_json.content_arr[i]['sub_comp_arr'][j]); It is saving a null value on my Json, Which I don't want. How to achieve it
You could use filter instead.
content_json.content_arr[i].sub_comp_arr = content_json.content_arr[i].sub_comp_arr.filter(q => q.value)
