Let's say i have this:
<form id='foo'>
<input name='bar[name]' />
<input name='bar[age]' />
</form>
How can i get the values of array inputs within the form foo and put them into an associative array/object like this:
var result = {bar:{name:'blah',age:21}};
P.S. I don't want to use any frameworks for this.
I needed to do this myself and after finding this question I didn't like any of the answers: I don't like regex and the others are limited.
You can get the data variable many ways. I'll be using jQuery's serializeArray method when I implement this.
function parseInputs(data) {
var ret = {};
retloop:
for (var input in data) {
var val = data[input];
var parts = input.split('[');
var last = ret;
for (var i in parts) {
var part = parts[i];
if (part.substr(-1) == ']') {
part = part.substr(0, part.length - 1);
}
if (i == parts.length - 1) {
last[part] = val;
continue retloop;
} else if (!last.hasOwnProperty(part)) {
last[part] = {};
}
last = last[part];
}
}
return ret;
}
var data = {
"nom": "123",
"items[install][item_id_4]": "4",
"items[install][item_id_5]": "16",
"items[options][takeover]": "yes"
};
var out = parseInputs(data);
console.log('\n***Moment of truth:\n');
console.log(out);
You can map the elements to an object like this.
function putIntoAssociativeArray() {
var
form = document.getElementById("foo"),
inputs = form.getElementsByTagName("input"),
input,
result = {};
for (var idx = 0; idx < inputs.length; ++idx) {
input = inputs[idx];
if (input.type == "text") {
result[input.name] = input.value;
}
}
return result;
}
var form = document.getElementById( 'foo' );
var inputs = form.getElementsByTagName( "input" );
var regex = /(.+?)\[(.+?)\]/;
var result = {};
for( var i = 0; i < inputs.length; ++i ) {
var res = regex.exec( inputs[i].name );
if( res !== null ) {
if( typeof result[ res[1] ] == 'undefined' ) result[ res[1] ] = {};
result[ res[1] ][ res[2] ] = inputs[i].value;
}
}
var inputs = document.getElementsByTagName('input');
var field_name, value, matches, result = {};
for (var i = 0; i < inputs.length; i++) {
field_name = inputs[i].name;
value = inputs[i].value;
matches = field_name.match(/(.*?)\[(.*)\]/);
if (!results[matches[0]]) {
results[matches[0]] = {};
}
results[matches[0]][matches[1]] = value;
}
This will get you the elements:
var result = {};
var elements = document.forms.foo.getElementsByTagName("input");
for(var i = 0; i < elements.length; i++)
{
/* do whatever you need to do with each input */
}

I am trying to re-populate a form from some values in localStorage. I can't quite manage the last part to get the loop to populate my name and values.
function loadFromLocalStorage() {
PROCESS_SAVE = true;
var store = localStorage.getItem(STORE_KEY);
var jsn = JSON.parse(store);
console.log(jsn);
if(store.length === 0) {
return false;
}
var s = jsn.length-1;
console.log(s);
for (var i = 0; i < s.length; i++) {
var formInput = s[i];
console.log(s[i]);
$("form input[name='" + formInput.name +"']").val(formInput.value);
}
}
Could I get some pointers please.
Your issue is in this section of code.
var s = jsn.length-1;
console.log(s);
for (var i = 0; i < s.length; i++) {
You are setting s to the length of the jsn array minus 1, then using it as if it were jsn. I think you intended something like this.
function loadFromLocalStorage() {
PROCESS_SAVE = true;
var store = localStorage.getItem(STORE_KEY);
var jsn = JSON.parse(store);
console.log(jsn);
if(store.length === 0) {
return false;
}
for (var i = 0; i < jsn.length; i++) {
var formInput = jsn[i];
console.log(jsn[i]);
$("form input[name='" + formInput.name +"']").val(formInput.value);
}
}
I have an object output from below code how to set the index start from 0 in js?
Object
3: Object
id: 34
type: 0
var obj = {};
var edited = false;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
obj[i] = {};
obj[i]['id'] = data_id;
obj[i]['type'] = data_type;
}
}
console.log(obj);
Needs more jQuery ?
var arr = $(".list").filter(function() {
return $(this).data('type') != 0;
}).map(function() {
return { id : $(this).data('id'), type : $(this).data('type') };
}).get();
FIDDLE
Actually if you want to start in 0, use another variable and not "i" (which I think is 3 when you use it as index).
var obj = {};
var edited = false;
var obj_idx = 0;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
obj[obj_idx] = {};
obj[obj_idx]['id'] = data_id;
obj[obj_idx]['type'] = data_type;
obj_idx += 1;
}
}
console.log(obj);
I think this time obj will be something like:
Object
0: Object
id: 34
type: 0
you could fake object as array by Array.prototype.push.call, in that way you could also gain the side effect: obj.length. it's kinda ninja and elegant :]
var obj = {};
var edited = false;
for (var i = 0; i < $(".list").length; i++) {
var data_id = parseInt($(".list").eq(i).attr('data-id'));
var data_type = parseInt($(".list").eq(i).attr('data-type'));
if ((data_type != 0)) {
edited = true;
} else {
edited = false;
}
if (edited == true) {
Array.prototype.push.call(obj, {id: data_id, type: data_type});
}
}
I am going to give a very simple and readable example. Say you've got an object with the following structure:
Object
0: Object
key: 'some-key'
value: 'some-value'
1: Object
...
Then you might want to delete an entry from it and reindex the whole thing, this is how I do it:
// obj is Object from above
const reIndexed = Object.entries(obj).map((element, index) => {
if (parseInt(element[0] != index) {
element[0] = index.toString();
}
return element;
});
I am creating array object like follows:
var numberOfSameDeficiency = [];
for (var i = 0; i < result.length; i++) {
var deficiencyId = result[i].Deficiency_Id;
var deficiencyName = result[i].DeficiencyName;
//check to see if this deficiency is already in the list of available selections
if ($("#drpDeficiency option[value='" + deficiencyId + "']").length == 0) {
var option = $('<option>');
option.attr('value', deficiencyId);
option.text(deficiencyName);
$select.append(option);
}
else {
Tests = {};
Tests.TestId = testId;
Tests.DeficiencyId = deficiencyId;
numberOfSameDeficiency.push(Tests);
}
}
And I want to remove object on different function like this:
for (var i = 0; i < result.length; i++) {
console.log(numberOfSameDeficiency);
var isFound = false;
var deficiencyId = result[i].Deficiency_Id;
if (numberOfSameDeficiency) {
numberOfSameDeficiency.forEach(function (entry) {
if (entry.DeficiencyId != deficiencyId) {
isFound = true;
**numberOfSameDeficiency.splice(entry, 1); // Generating Error (Remove all items from array object)**
return;
}
});
// console.log("end if");
}
if (!isFound) {
$("#drpDeficiency option[value='" + deficiencyId + "']").remove();
}
}
So what line code should be there to remove particular object from array object.
Try this
for( i=myArray.length-1; i>=0; i--) {
if( myArray[i].field == "money") myArray.splice(i,1);
}
This also works
myArray = [{name:"Alpesh", lines:"2,5,10"},
{name:"Krunal", lines:"1,19,26,96"},
{name:"Deep",lines:"3,9,62,36" }]
johnRemovedArray = myArray
.filter(function (el) {
return el.name !== "Krunal";
});
Create this prototype function:
Array.prototype.removeElement = function (el) {
for(let i in this){
if(this.hasOwnProperty(i))
if(this[i] === el)
this.splice(i, 1);
}
}
Then call:
let myArray = ['a','b','c','d'];
myArray.removeElement("c");
It also works with objects:
let myObj1 = {name: "Mike"},
myObj2 = {name: "Jenny"},
myArray = [myObj1, myObj2];
myArray.removeElement(myObj2);
I'm really new to JS, and I'm now stuck on a task, hope someone can guide me through it.
I have an Array of Objects, like this one:
var labels = [
// labels for pag 1
{pageID:1, labels: [
{labelID:0, content:[{lang:'eng', text:'Txt1 Eng'}, {lang:'de', text:'Txt1 De:'}]},
{labelID:1, content:[{lang:'eng', text:'Txt 2 Eng:'}, {lang:'de', text:'Txt2 De:'}]},
{labelID:2, content:[{lang:'eng', text:'Txt 3 Eng:'},{lang:'de', text:'Txt 3 De:'}]}
]},
// labels for pag 2
{pageID:2, labels: [
{labelID:0, content:[{lang:'eng', text:'Txt1 Eng'}, {lang:'de', text:'Txt1 De:'}]},
{labelID:1, content:[{lang:'eng', text:'Txt 2 Eng:'}, {lang:'de', text:'Txt2 De:'}]},
{labelID:2, content:[{lang:'eng', text:'Txt 3 Eng:'},{lang:'de', text:'Txt 3 De:'}]}
]}
]
What I am trying to do is write a function to return me an array of labels (Objects) for a specific page and a specific lang. By calling this function specifying pageID 1 and lang eng, I'm basically trying to build an array like this one:
var desideredArray = [
{labelID:0, text:'Txt1 Eng'},
{labelID:1, text:'Txt1 Eng'},
{labelID:2, text:'Txt2 Eng'}
]
Now, I'm trying to write the function to retrieve/build the new array:
this.getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function( obj ) {
return obj.pageID == numPage;
});
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
// simpleLabelObject.text = ?????
results[i] = simpleLabelObject;
}
console.log (results);
};
...but how can I access the right value (the one corresponding the lang selected) in the content property?
You can use the same technique as the one used to keep the matching page: the filter method.
this.getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function( obj ) {
return obj.pageID == numPage;
});
var contentFilter = function(obj){ return obj.lang === lang};
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var matching = tempResult[i].content.filter(contentFilter);
simpleLabelObject.text = matching[0].text;
desiredResults[i] = simpleLabelObject;
}
console.log (desiredResults);
};
I didn't do bound checks because in your code you assumed there is always a matching element, but it would probably be wise to do it.
And if you want to avoid creating two closures each time the function is called, you can prototype an object for that:
var Filter = function(numPage, lang) {
this.numPage = numPage;
this.lang = lang;
};
Filter.prototype.filterPage = function(obj) {
return obj.pageID === this.numPage;
}
Filter.prototype.filterLang = function(obj) {
return obj.lang === this.lang;
}
Filter.prototype.filterLabels = function(labels) {
var result = labels.filter(this.filterPage, this);
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i=0; i<tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var matching = tempResult[i].content.filter(this.filterLang, this);
simpleLabelObject.text = matching[0].text;
desiredResults[i] = simpleLabelObject;
}
return desiredResults;
}
console.log(new Filter(1, "eng").filterLabels(labels));
Just filter again:
var getLabelsForPageAndLang = function (numPage, lang) {
// this part filters the main object and selects the object with pageID == numPage
var result = labels.filter(function (obj) {
return obj.pageID == numPage;
});
var tempResult = result[0].labels;
var desiredResults = []; // here I want to store the new objects
for (var i = 0; i < tempResult.length; i++) {
var simpleLabelObject = {};
simpleLabelObject.labelID = tempResult[i].labelID;
var lg = tempResult[i].content.filter(function (lg) {
return lg.lang == lang;
});
simpleLabelObject.text = lg[0].text;
desiredResults.push(simpleLabelObject);
}
console.log(desiredResults);
};

A rather 'safe' implementation for cases when pages have the same pageID and multiple contents with the same lang:
this.getLabelsForPageAndLang = function(numPage, lang) {
var result = [];
var pages = labels.filter(function( obj ) {
return obj.pageID === numPage;
});
for (var p = pages.length - 1; p >= 0; p--) {
var page = pages[p];
for(var i = page.labels.length - 1; i >= 0; i--) {
var labelId = page.labels[i].labelID;
for (var j = page.labels[i].content.length - 1; j >= 0; j--){
if (page.labels[i].content[j].lang === lang) {
result.push({labelID: labelId, test: page.labels[i].content[j].text});
}
}
}
}
console.log(result);
}

Im currently working on this script that is written in javascript that returns data from the netsuite ERP platform.
Right now we have the code returning in an array, whilst this is good, it is a result of a dataset of product information.
The script is querying for 3 products, and as a result it returns an array of 21 keys.
this should be returning 3 arrays of arrays so we can handle the content easily externally to Netsuite.
I for the life of me cant figure out which loop I am required to create a new array to manage the content.
function loadRecord(request, response)
{
var recType = request.getParameter('recType');
var savedSearchId = request.getParameter('savedSearchId');
var internalid = request.getParameter('internalid');
//perform the required search.
var filter = [];
if(recType == 'customer' || recType == 'contact' )
{
filter[0] = new nlobjSearchFilter('internalid', null, 'is', internalid); // just get the 1 item by the internal id of the record
}
if( recType == 'item')
{
var internal_ids = new Array();
internal_ids[0] = 25880;
internal_ids[1] = 25980;
internal_ids[2] = 333 ;
filter[0] = new nlobjSearchFilter('internalid', null, 'anyOf', internal_ids); // just get the 1 item by the internal id of the record
}
if(recType == 'transaction')
{
filter[0] = new nlobjSearchFilter('type',null,'anyOf','SalesOrd');
filter[1] = new nlobjSearchFilter('internalid','customer','is', internalid );
}
var rsResults = nlapiSearchRecord(recType, savedSearchId, filter);
var rsObj = [];
// not sure how to make each row a new array of arrays so it is structured more elegantly...
for (x = 0; x < rsResults.length; x++)
{
var flds = rsResults[x].getAllColumns();
for (i = 0; i < flds.length; i++)
{
var rowObj = {};
rowObj.name = flds[i].getName();
rowObj.label = flds[i].getLabel();
rowObj.val = rsResults[x].getValue(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary());
rowObj.txtval = rsResults[x].getText(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary())
rsObj.push(rowObj);
}
}
response.write(JSON.stringify(rsObj));
}
Any help greatly appreciated
Is this what you're looking for?
var rsObj = [];
var rowArr, fields, x, i;
for (x = 0; x < rsResults.length; x++)
{
flds = rsResults[x].getAllColumns();
for (i = 0; i < flds.length; i++)
{
rowArr = rsObj[x] = [];
rowArr.push(flds[i].getName());
rowArr.push(flds[i].getLabel());
rowArr.push(rsResults[x].getValue(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary()));
rowArr.push(rsResults[x].getText(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary()));
}
}
console.log(rsObj[0][0]); // row0.name
console.log(rsObj[2][1]); // row2.label
Maybe something like this:
for (var x = 0; x < rsResults.length; x++)
{
var flds = rsResults[x].getAllColumns();
for (var i = 0; i < flds.length; i++)
{
rsObj.push({
name: flds[i].getName(),
label: flds[i].getLabel(),
val: rsResults[x].getValue(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary()),
txtval: rsResults[x].getText(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary())
});
}
}
If you are using ECMAScript5, you cold simplify the loop with forEach, like this:
rsResults.forEach(function(result) {
result.getAllColumns().forEach(function(fields) {
rsObj.push({
name: fields.getName(),
label: fields.getLabel(),
val: result.getValue(fields.getName(), fields.getJoin(), fields.getSummary()),
txtval: result.getText(fields.getName(), fields.getJoin(), fields.getSummary())
});
});
});
This must solve you problem. Some declaration problem might be there.
var rsObj = [];
for (int x = 0; x < rsResults.length; x++)
{
var flds = rsResults[x].getAllColumns();
for (int i = 0; i < flds.length; i++)
{
var rowObj = [];
rowObj.push(flds[i].getName());
rowObj.push(flds[i].getLabel());
rowObj.push(rsResults[x].getValue(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary()));
rowObj.push(rsResults[x].getText(flds[i].getName(), flds[i].getJoin(), flds[i].getSummary()));
rsObj.push(rowObj);
}
}
