Create an array of search results-CodePudding

How can i get the name in the picture below?

  return testData.then((data) => {
    console.log(data)
    var results = [];
    var toSearch = params.suggestTerm;
    data = data["data"]["0"];
    console.log("data: ", data["0"])
    for(var i=0; i<data.length; i  ) {
      if(data[i]["name"].indexOf(toSearch)!=-1) {
        results.push(data[i]);
      }
    }

result of console.log(data)

No need to do this :data = data["data"]["0"];. If you are doing that you are assigning data to be the first object from the nested list. It is not an array anymore.

Just get the list in another variable and access that:

 let list = data.data;
 for(var i=0; i<list.length; i  ) {
      if(list[i]["name"].indexOf(toSearch) !== -1) {
        results.push(list[i]);
      }
    }

The indexOf() search will be case sensitive. If that is not what you want, you can lowercase and search.

It appears you are looking to have an array only containing items that have name values in your toSearch string. If that's the case, you could use Array.filter() similar to:

return testData.then((data) => {
    console.log(data)
    var results = [];
    var toSearch = params.suggestTerm;
    if (data && data.data && data.data.length > 0){
        results = data.data.filter(item =>
            item.name.toLowerCase().indexOf(toSearch.toLowerCase()) > -1
       )
    return results;
}

This example searches case insensitive. If you wish for a case sensitive search, remove the .toLowerCase()
