How to get the label value in javascript - javascript

I am creating a dynamic tr/td based on json data using below code.
for (i = 0; i < dataPoolJSON.length; i++) {
html += "<tr id ='row" + i + "' value ='" + dataPoolJSON[i].msisdn + "'><td><div class='group'><label id='label" + i + "' for='numView" + dataPoolJSON[i].msisdn + "' class='ch-control'>";
html += "<input id='numView" + dataPoolJSON[i].msisdn + "' type='radio' class='iradio_minimal' value='" + i + "' name='msisdnSelected'/>" + dataPoolJSON[i].msisdn;
html += "</label></div></td><td class='hidden-xs'><a id='viewUsage" + i + "' class='viewUsage' onclick='viewDataPoolUsage(this," + dataPoolJSON[i].msisdn + ");return false;' href=''>View Usage</a>";
html += "<div class='pool-usage hidden'></div></td>";
html += "<td><span id='dataAllowed" + i + "'><select>";
if (dataPoolJSON[i].userSetting != null) {
html += "<option selected='selected' value='" + dataPoolJSON[i].userSetting.alertPercentageData1 + "'>" + dataPoolJSON[i].userSetting.alertPercentageData1 + "</option>";
}
html += "</select></span></td></tr>";
}
$('#data-pool tbody').html(html);
Now on click on radio button i need to fetch the msisdn value and current option selected value as but it is not giving me required answer. I am getting the current option selected value but not the msisdn.
function submitNewDataUsagealerts() {
var jsonSubmitData = [];
var selectedData = document.getElementsByName("msisdnSelected");
var i = selectedData.length-1;
for ( j=0; j <= i; j++ ) {
if(selectedData[j].checked) {
var valueCurrent = $('#dataAllowed'+selectedData[j].value).find('option:selected').val();
var row = $('#label'+selectedData[j].value).val();
item = {}
item [0] = valueCurrent;
item [1] = selectedData[j].value;
}
}
}


To get the "value" from a label, use .text() rather than .val().
var row = $('#label'+selectedData[j].value).text();
As your label includes an input and the required text, you can put the text inside a container so that it can be referenced without including the input:
The label code is currently (irrelevant code removed) :
html += "<label id='label" + i + "' for='numView" + dataPoolJSON[i].msisdn + "' class='ch-control'>";
html += "<input id='numView" + dataPoolJSON[i].msisdn + "' type='radio' class='iradio_minimal' value='" + i + "' name='msisdnSelected'/>";
html += dataPoolJSON[i].msisdn;
html += "</label>";
change this to:
html += "<label id='label" + i + "' for='numView" + dataPoolJSON[i].msisdn + "' class='ch-control'>";
html += "<input id='numView" + dataPoolJSON[i].msisdn + "' type='radio' class='iradio_minimal' value='" + i + "' name='msisdnSelected'/>" ;
html += "<span>" + dataPoolJSON[i].msisdn + "</span>";
html += "</label>";
Then your selector can be:
var row = $('#label'+selectedData[j].value + ">span").text();
Alternatively, move the input out of the label as you're already using label for=:
html += "<input id='numView" + dataPoolJSON[i].msisdn + "' type='radio' class='iradio_minimal' value='" + i + "' name='msisdnSelected'/>" ;
html += "<label id='label" + i + "' for='numView" + dataPoolJSON[i].msisdn + "' class='ch-control'>";
html += dataPoolJSON[i].msisdn
html += "</label>";
Then your selector can be:
var row = $('#label'+selectedData[j].value).text();


var msg = document.getElementById('lbltxt').innerHTML;
alert(msg);
<label id="lbltxt" style="display:none">Test</label>


HTML Code
<label id="mylabel" />
JS Code
var lavelValue = $("#mylabel").text();

convert a dynamically created table cell to a text box when clicked

I have dynamically generated table using jquery. I want a cell of the table be converted to a textbox when clicked.
$.each(proc_msg, function (i, item) {
trHTML += "<tr><td>" + item.hq_code + "</td><td id='hq_" + item.hq_name + "'>" + item.hq_name + "</td>";
trHTML += "<td><a href='#' id='hq_ed_" + item.hq_name+_"' onClick='dataAction(this.id);'>Edit</span></a></td>";
});
$('#tbl_hqlist').append(trHTML);
function dataAction(dataValue){
var sectionName=dataValue.substr(0,2);
var hq_zone=dataValue.substr(5);
var zone_id ="";
zone_id= zone_id.concat("'#",sectionName, hq_zone,"'");
var tempHTML ="<input type='text' id='" + zone_id + "' value='" + hq_zone + "' />";
$(zone_id).html(tempHTML);
}
This code is throwing up error where "zone_id" is not defined.

javascript find delta of modified form data

I have an html and javascript page rendered through python django, where I have a form data of 30 entries maximum in each page, that can be edited. I included a hidden field with the same form data to extract the old, and modified values in the form. I am looking for extracting just the delta (old and new values for the field that was changed). My code is
{%extends 'base.html'%}
{%block content%}

var input = document.getElementsByName("new"+id);
if(btn.value=="Edit") {
//var input = document.getElementsByName("name"+id);
for(i = 0;i < input.length; i++) {
document.getElementById(input[i].id).removeAttribute("Readonly");
} //End of for loop
document.getElementById(id).value="Save";

What is the best way to do this?

Building HTML table in javascript, getting "ReferenceError: invalid assignment left-hand side"

I hope someone can help me out with this. I'm trying to dynamically build an HTML table in javascript/jquery based on iterating over an array built by earlier code. I am getting an error on the referenced line below as soon as the page loads:
function BuildForm (allFields) {
var dyndata = "";
var formstart = "<form>\n<fieldset class='fieldset-js'>\n<legend>Choose A Parent</legend>\n<table class='table-js'>\n<tr>\n<th class='th'>ID</th>\n<th class='th'>Name</th>\n<th class='th'>DOB</th>\n<th class='th'>Phone</th>\n</tr>\n<tr>";
$('#PickAParent-Form').append(formstart);
$.each(allFields, function (index, value) {
if ((index + 5) % 5 == 0) {
dyndata = "<tr>\n<td class='td1'><input type='radio' name='pid' value='" = index + "'>" + value + "</td>\n";
error here---------^
$('#PickAParent-Form').append(dyndata);
} elseif ((index +1 ) % 5 == 0) {
dyndata = "<td class='td1'>" + value + "</td>\n</tr>\n";
$('#PickAParent-Form').append(dyndata);
} else {
dyndata = "<td class='td1'>" + value + "</td>\n";
$('#PickAParent-Form').append(dyndata);
}
});
DisplayForm;
}
I have been all over Google and SO this AM but can't figure this one out. Any help is MUCH appreciated!!

This line:
dyndata = "<tr>\n<td class='td1'><input type='radio' name='pid' value='" = index + "'>" + value + "</td>\n";
should be:
dyndata = "<tr>\n<td class='td1'><input type='radio' name='pid' value='" + index + "'>" + value + "</td>\n";
Looks like you had an equals sign instead of a plus sign for variable to string conversion

Change it to:
dyndata = "<tr>\n<td class='td1'><input type='radio' name='pid' value='" + index + "'>" + value + "</td>\n";
Note:
value='" + index + "'
Instead of:
value='" = index + "'

Dynamically create and assign id to an input?

My code is below but I'm unable to verify if it's correct, or if it is, why I can't access the created text inputs by id
for (i=0;i<t;i++)
{
div.innerHTML=div.innerHTML+"<input id="+i+"\" type='text' value="+(i+1)+">"+"<br>";
div1.innerHTML=div1.innerHTML+"<input id=a"+i+"\" type='text' value=a"+(i+1)+">"+"<br>";
gont.innerHTML=gont.innerHTML+i;
}

var t = 2;
var div = document.getElementById('idDiv');
for (i = 0; i < t; i++) {
div.innerHTML = div.innerHTML + "<input id=" + i + "\" type='text' value=" + (i + 1) + ">" + "<br>";
div1.innerHTML = div1.innerHTML + "<input id=a" + i + "\" type='text' value=a" + (i + 1) + ">" + "<br>";
gont.innerHTML = gont.innerHTML + i;
}

why this javascript function is not executing, no error in console

This function is a problem:
function addInvoiceItemValue(name,pkwiu,netto,unit,qty,vat) {
if(vat == '23') v23 = " selected='selected'";
if(vat == '22') v22 = " selected='selected'";
if(vat == '8') v8 = " selected='selected'";
if(vat == '7') v7 = " selected='selected'";
if(vat == '5') v5 = " selected='selected'";
if(vat == '3') v3 = " selected='selected'";
if(vat == '0') v0 = " selected='selected'";
if(vat == 'zw') vzw = " selected='selected'";
var vatSelect = "<option value='23'"+v23+">23%</option><option value='22'"+v22+">22%</option><option value='8'"+v8+">8%</option><option value='7'"+v7+">7%</option><option value='5'"+v5+">5%</option><option value='3'"+v3+">3%</option><option value='0'"+v0+">0%</option><option value='zw'"+vzw+">zw.</option>";
var row = "<tr id='item" + itemID + "'><td><input size='30' maxlength='300' id='ii-name-" + itemID + "' name='ii-name-" + itemID + "' value='" + name + "'></td>";
row += "<td><input size='6' maxlength='50' id='ii-pkwiu-" + itemID + "' name='ii-pkwiu-" + itemID + "' value='"+pkwiu+"'></td>";
row += "<td><input size='6' maxlength='16' id='ii-netto-" + itemID + "' name='ii-netto-" + itemID + "' value='"+netto+"'></td>";
row += "<td><input size='5' maxlength='128' id='ii-unit-" + itemID + "' name='ii-unit-" + itemID + "' value='"+unit+"'></td>";
row += "<td><input size='5' maxlength='6' id='ii-qty-" + itemID + "' name='ii-qty-" + itemID + "' value='"+qty+"'></td>";
row += "<td><select id='ii-vat-" + itemID + "' name='ii-vat-" + itemID + "'>" + vatSelect + "</select></td>";
row += "<td><a onclick='delInvoiceItem(\"item" + itemID + "\")'><b>-</b> Usuń</a></td></tr>";
$('#invoiceItems tr:last').after(row);
itemID++;
}
Example execution:
addInvoiceItemValue('yyy','','676.76','','1','23');
addInvoiceItemValue('fgh','','777.00','','1','8');
And here is function that work's fine:
function addInvoiceItem() {
var vatSelect = "<option value='23'>23%</option><option value='22'>22%</option><option value='8'>8%</option><option value='7'>7%</option><option value='5'>5%</option><option value='3'>3%</option><option value='0'>0%</option><option value='zw'>zw.</option>";
var row = "<tr id='item" + itemID + "'><td><input size='30' maxlength='300' id='ii-name-" + itemID + "' name='ii-name-" + itemID + "' value=''></td>";
row += "<td><input size='6' maxlength='50' id='ii-pkwiu-" + itemID + "' name='ii-pkwiu-" + itemID + "' value=''></td>";
row += "<td><input size='6' maxlength='16' id='ii-netto-" + itemID + "' name='ii-netto-" + itemID + "' value='0'></td>";
row += "<td><input size='5' maxlength='128' id='ii-unit-" + itemID + "' name='ii-unit-" + itemID + "' value=''></td>";
row += "<td><input size='5' maxlength='6' id='ii-qty-" + itemID + "' name='ii-qty-" + itemID + "' value='1'></td>";
row += "<td><select id='ii-vat-" + itemID + "' name='ii-vat-" + itemID + "'>" + vatSelect + "</select></td>";
row += "<td><a onclick='delInvoiceItem(\"item" + itemID + "\")'><b>-</b> Usuń</a></td></tr>";
$('#invoiceItems tr:last').after(row);
itemID++;
}

The v23, v22, v8, v7, v5, v3, v0, vzw and itemdID are not always defined in all code paths.
This causes the script to fail.
You should change your function to
function addInvoiceItemValue(name,pkwiu,netto,unit,qty,vat) {
var vats = ['23','22','8','7','5','3','0','zw'];
var vatSelect = '';
for (var i = 0; i < vats.length; i++)
{
vatSelect += '<option value="'+vats[i]+'"';
if (vat == vats[i])
vatSelect += ' selected="selected"';
vatSelect += '>'+vats[i] + '%</option>';
}
var row = "<tr id='item" + itemID + "'><td><input size='30' maxlength='300' id='ii-name-" + itemID + "' name='ii-name-" + itemID + "' value='" + name + "'></td>";
row += "<td><input size='6' maxlength='50' id='ii-pkwiu-" + itemID + "' name='ii-pkwiu-" + itemID + "' value='"+pkwiu+"'></td>";
row += "<td><input size='6' maxlength='16' id='ii-netto-" + itemID + "' name='ii-netto-" + itemID + "' value='"+netto+"'></td>";
row += "<td><input size='5' maxlength='128' id='ii-unit-" + itemID + "' name='ii-unit-" + itemID + "' value='"+unit+"'></td>";
row += "<td><input size='5' maxlength='6' id='ii-qty-" + itemID + "' name='ii-qty-" + itemID + "' value='"+qty+"'></td>";
row += "<td><select id='ii-vat-" + itemID + "' name='ii-vat-" + itemID + "'>" + vatSelect + "</select></td>";
row += "<td><a onclick='delInvoiceItem(\"item" + itemID + "\")'><b>-</b> Usuń</a></td></tr>";
$('#invoiceItems tr:last').after(row);
itemID++;
}
but the itemID also has to be defined.

When is it SUPPOSED to be executing?
While this technically bad coding practice, test with this:
<a href='#' onClick="javascript: function('value');" > Click Me </a>
If you click, and it still doesn't work, it is an issue with your function. If you click and it works, the function is never being called in the first place.

You should also check your selector.
$('#invoiceItems tr:last').after(row);
Try adding it in a simpler place. Make another div,...
Then use the selector $('#result');
In any case, if your selector is bad, it will never execute and it won't throw an error b/c it never had cause to do what you told it. Now that I think about it, I think this is the issue.
Do me a favor and try
$('#invoiceItems tr:last').each(alert('exist???'));
If it doesn't alert, your selector is most likely not working. (For each thing that meets the criteria , do an alert)
