How to take create, using Javascript, an Index in Elasticsearch with rows' name taken from an array?
Question
I want to create an Index in Elasticsearch using Javascript. The name of each column is in a different position of an array and every field of each row in another array. How should I "fill" the body of the index? Let's say a have:
arr_1 = [row1, row2, row3, row4];
arr_2 = [field1, field2, field3, field4];
then I want something like:
client.index(
index: name_index,
type: name_type,
body: {
row1 : field1; //arr1_[1] : arr_2[1],
row2 : field2; //arr1_[2] : arr_2[2],
.....
....
}
)

This seems to accomplish what you want, if I'm understanding you correctly:
var arr_1 = ["row1", "row2", "row3", "row4"];
var arr_2 = ["field1", "field2", "field3", "field4"];
var doc_body = {};
arr_1.map(function(val, idx){ doc_body[val] = arr_2[idx]; });
client.index({
index: 'test_index',
type: 'mytype',
id: '1',
body: doc_body
});
Here is a self-contained html document that implements it:
<html>
<head>
<script src="http://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/elasticsearch/3.0.2/elasticsearch.jquery.min.js"></script>
</head>
<body>
<div><button id="delete_index_btn">Delete Index</button></div>
<div><button id="create_index_btn">Create Index</button></div>
<div><button id="add_docs_btn">Add Docs</button></div>
<div>
<h3>Response:</h3>
<pre id="response"></pre>
</div>
<script type="text/javascript">
$(function(){
var client = new $.es.Client({
hosts: 'localhost:9200'
});
$("#delete_index_btn").click(function(){
client.indices.delete({
index: 'test_index'
}).then(function(resp){
$("#response").append("\nclient.indices.delete: " + JSON.stringify(resp));
}, function(err){
$("#response").append("\nclient.indices.delete ERROR: " + JSON.stringify(err));
});
});
$("#create_index_btn").click(function(){
client.indices.create({
index: 'test_index'
}).then(function(resp){
$("#response").append("\nclient.indices.create: " + JSON.stringify(resp));
}, function(err){
$("#response").append("\nclient.indices.create ERROR: " + JSON.stringify(err));
});
});
$("#add_docs_btn").click(function(){
var arr_1 = ["row1", "row2", "row3", "row4"];
var arr_2 = ["field1", "field2", "field3", "field4"];
var doc_body = {};
arr_1.map(function(val, idx){ doc_body[val] = arr_2[idx]; });
client.index({
index: 'test_index',
type: 'mytype',
id: '1',
body: doc_body
}).then(function(resp){
$("#response").append("\nclient.index: " + JSON.stringify(resp));
}, function(err){
$("#response").append("\nclient.index ERROR: " + JSON.stringify(err));
});
});
});
</script>
</body>
</html>
Does that solve your problem?

Thank you, I solved using this:
var doc_body= {};
for(i = 0; i = arr_1.length; i++){
doc_body[arr_1[i]] = arr_2[i];
}
client.index({
index: 'test_index',
type: 'mytype',
id: '1',
body: doc_body
});
