I am having table below.. but Getting wrong calculation in javascript..
<script>
function getPrice(tRate, tMaking, tHandeling, tPrice, tVat, tQuantity, tTotal) {
var obj_tRate = document.getElementById(tRate)
var obj_tMaking = document.getElementById(tMaking)
var obj_tHandeling = document.getElementById(tHandeling)
var obj_tPrice = document.getElementById(tPrice)
var obj_tVat = document.getElementById(tVat)
var obj_tTotal = document.getElementById(tTotal)
var obj_tQuantity = document.getElementById(tQuantity)
if (obj_tRate.value != "" && obj_tMaking.value != "" && obj_tHandeling.value != "") {
obj_tPrice.value = parseFloat(obj_tRate.value) + parseFloat(obj_tMaking.value) + parseFloat(obj_tHandeling.value);
console.log(obj_tPrice.value)
obj_tVat.value = parseFloat(obj_tPrice.value * (1 / 100));
console.log(obj_tVat.value)
obj_tTotal.value = parseFloat(obj_tVat.value + (obj_tPrice.value * obj_tQuantity.value));
console.log(obj_tTotal.value)
}
else {
obj_tPrice.value = "";
}
}

Use parseFloat on the operands, not on the result of the computation.
For example, replace
obj_tTotal.value = parseFloat(obj_tVat.value + (obj_tPrice.value * obj_tQuantity.value));
with
var tPrice = parseFloat(obj_tPrice.value);
var tQuantity = parseFloat(obj_tQuantity.value);
obj_tTotal.value = tPrice + tPrice * tQuantity;
When you add, like you did, a string and a number, you do a string concatenation.
For example
"1000" + "5" * "100"
gives
"1000" + 500
which is
"1000500"
At this point, it's too late to call parseFloat.

I have a large-ish code that I am working with. My problem is that I have multiple tables/arrays that I'm not sure how to group under one script tag so they all have their own. My tables work okay separately, but I know the code is convoluted. I can't figure out the array. It was supposed to be a 3x5 array, but when it shows up on the page its all one column and one row. Another issue is that when I try to globally declare the array, the text itself shows up in the html rather than executing properly.

I'm really frustrated trying to get my html and javascript code to work together. I am trying to get the user information from the storeClientData() to print on top of the reservationMessage. I have been working on it for the last 4 hours with no luck. Any help would be much appreciated.
I want to get a output that would show like:
Mr. Firstname, Lastname, street, city, province/state, country, contact info.
Then:
Car size and price, options(ex. navigation), duration in days, cost of rental.

You didn't add id="customerResult" attribute in HTML and also you didn't invoke storeClientData() function from HTML. That's the reason why you couldn't get user information from storeClientData() function and couldn't print it top of the reservation form.
I added <input type=button value="storeClientData" onClick="storeClientData(); return false;"> element before registeration button element in HTML and <div id="customerResult"></div> element top of the reservation form.
You can refer final code in jsfiddle link http://jsfiddle.net/ADukg/10171/.
How do I sum the two highest values from a list of inputs using JavaScript?
I've tried the below, but I get 4 instead of 5:
<table id="tableID">
<tr>
<td> <input name="name" class="compulsory1" type="text" value="1" /> </td>
<td> <input name="name1" class="compulsory1" type="text" value="3" /> </td>
<td> <input name="name2" class="compulsory1" type="text" value="2" /> </td>
<td>
<script type="text/javascript">
var tdsCompulsory = document.getElementsByClassName('compulsory1');
var len = tdsCompulsory.length;
var cDatax = [];
var cData = cDatax.reverse();
sum = 0;
for(var i = 0; i < 2; i++){
cData.push(tdsCompulsory[i].value);
sum += +tdsCompulsory[i].value;
}
alert (sum);
</script>
</td>
</tr>
</table>
First you find the two highest values, and then sum them together. I'd probably do it something like this:
document.getElementById("the-button").onclick = function() {
// Get the values as numbers
var values = Array.prototype.map.call(
document.getElementsByClassName('compulsory1'),
function(input) {
return +input.value; // + converts to number
}
);
// Put them in order *highest* to *lowest*
values.sort(function(left, right) {
return right - left;
});
// Add the first two
var result = values[0] + values[1];
console.log(values[0] + " + " + values[1] + " = " + result);
};
<input name="name" class="compulsory1" type="text" value="1" />
<input name="name1" class="compulsory1" type="text" value="3" />
<input name="name2" class="compulsory1" type="text" value="2" />
<input id="the-button" type="button" value="Run">
More about that Array.prototype.map.call thing in this answer about looping through arrays and array-like things.
But if you specifically want to use reverse, you'd do that after the sort:
document.getElementById("the-button").onclick = function() {
// Get the values as numbers
var values = Array.prototype.map.call(
document.getElementsByClassName('compulsory1'),
function(input) {
return +input.value; // + converts to number
}
);
// Put them in order lowest to highest
values.sort(function(left, right) {
return left - right;
});
// Then reverse that
values.reverse();
// Add the first two
var result = values[0] + values[1];
console.log(values[0] + " + " + values[1] + " = " + result);
};
<input name="name" class="compulsory1" type="text" value="1" />
<input name="name1" class="compulsory1" type="text" value="3" />
<input name="name2" class="compulsory1" type="text" value="2" />
<input id="the-button" type="button" value="Run">
You could try something like following:
function PickTwoHighestCtrl() {
let els = document.querySelectorAll(".compulsory1");
let values = Array.prototype.map.call(els, (el) => {
return Number(el.value) || 0;
});
let highest = Math.max.apply(Math, values);
let secondHighest = Math.max.apply(
Math, values.filter(e => e !== highest)
);
console.log("Two highest values are:", highest, secondHighest, "and their sum is", highest + secondHighest)
}
document.addEventListener("DOMContentLoaded", PickTwoHighestCtrl);
<input class="compulsory1" type="text" value="1" />
<input class="compulsory1" type="text" value="3" />
<input class="compulsory1" type="text" value="2" />

for(var i = 0; i < 3; i++){

}
// let's convert it to a real array of numbers, not of strings :
var intArray = cDatax.map(Number);
var max = Math.max.apply(null, intArray);
// now let's sort it and take the second element :
var second = intArray.sort(function(a,b){return b-a})[1];
var sum = max+second;

You can try something like this:
Steps
Get all elements
Get their values. Note, since you expect values to be number, yuo should parse them as well.
Sort value array in descending order instead of .sort + .reverse
Calculate your sum
Sample
// Get all elements
var tdsCompulsory = document.getElementsByClassName('compulsory1');
// Get values from all elements
var valArr = Array.prototype.map.call(tdsCompulsory, function(el) {
return parseInt(el.value)
});
// Sort value array in descending order
var cDatax = valArr.sort(function(a, b) {
return b-a
});
var sum = cDatax[0] + cDatax[1];
console.log(sum)
<table id="tableID">
<tr>
<td>
<input name="name" class="compulsory1" type="text" value="1" />
</td>
<td>
<input name="name1" class="compulsory1" type="text" value="3" />
</td>
<td>
<input name="name2" class="compulsory1" type="text" value="2" />
</td>
</tr>
</table>
var tdsCompulsory = document.getElementsByClassName('compulsory1'),
cDatax = Array.prototype.map.call(tdsCompulsory, function(el) {
return parseInt(el.value) || 0;
}),
sum = 0;
cDatax
.sort(function(a, b){
return a - b;
})
.reverse();
sum = cDatax[0] + cDatax[1];
console.log(sum);
<table id="tableID">
<tr>
<td><input name="name" class="compulsory1" type="text" value="1" /></td>
<td><input name="name1" class="compulsory1" type="text" value="3" /></td>
<td><input name="name2" class="compulsory1" type="text" value="2" /></td>

Trying to calculate a selection value from a radio group and values from other fields. Any 'Name' input adds a value to the Total. I need the value from the radio group to be added to that total.
Here is the HTML:
<FORM NAME="testauthorization" ACTION="" METHOD=POST id="exhibitreg">
<table>
<tr>
<td><label>
<input type="radio" name="sponsorship" value="3000" id="sponsor1" />
$3,000</label>
<br />
<label>
<input type="radio" name="sponsorship" value="1500" id="sponsor2" />
$1,500</label>
<br />
<label>
<input type="radio" name="sponsorship" value="1000" id="sponsor3" />
$1,000</label>
<br /></td>
</tr>
<tr>
<td>Name 1 <INPUT NAME="Name_1" TYPE="TEXT" id="name1" onchange="updatecost(1, 50)" onkeyup="updatecost(1, 50)" VALUE="" size="30"></td>
<td><INPUT NAME="cost_1" TYPE="TEXT" VALUE="" size="4" id="cost1"></td>
</tr>
<tr>
<td>Name 2<INPUT NAME="Name_2" TYPE="TEXT" id="name2" onchange="updatecost(2, 50)" onkeyup="updatecost(2, 50)" VALUE="" size="30"></td>
<td><INPUT NAME="cost_2" TYPE="TEXT" VALUE="" size="4" id="cost2"></td>
</tr>
<tr>
<td>Name 3<INPUT NAME="Name_3" TYPE="TEXT" id="name3" onchange="updatecost(3, 50)" onkeyup="updatecost(3, 50)" VALUE="" size="30"></td>
<td><INPUT NAME="cost_3" TYPE="TEXT" VALUE="" size="4" id="cost3"></td>
</tr>
<tr>
<td colspan="4">Total:
<INPUT NAME="Total" id="Total" TYPE="TEXT" VALUE="" size="8" onFocus="this.form.elements[0].focus()" >
<INPUT TYPE="HIDDEN" onchange="totalcost()" onkeyup="totalcost()"></td>
</tr>
</table>
<INPUT TYPE="SUBMIT" VALUE="Submit">
<input type="RESET" name="Reset" value="Reset" />
</FORM>
And here is the JS:
<script language="JavaScript" type="text/javascript">
function getRadioValue(name) {
var group = document.getElementsByName('sponsorship');
for (var i=0;i<group.length;i++) {
if (group[i].checked) {
return group[i].value;
}
}
return '';
}
function updatecost(num, dollars) {
var text = document.getElementById("name" + num);
var cost = document.getElementById("cost" + num);
if (!text) return;
if (!cost) return;
if (text.value == "") {
cost.value = "";
}
else {
cost.value = dollars;
}
totalcost();
}
function totalcost() {
var total = 0;
for (var i = 1; i <= 3; i++) {
var cost = document.getElementById("cost" + i);
if (cost.value) total += Number(cost.value);
}
document.getElementById("Total").value = total;
}
//-->
</script>
What am I missing? By the way, in case it is not clear, I am a JS novice, so I fully accept criticism that helps me understand a more fundamental error in my approach. Simple is best for me: ;-) Thank you in advance.
Change below function in place of existing
function updatecost(num, dollars) {
var text = document.getElementById("name" + num);
var cost = document.querySelector('input[name="sponsorship"]:checked');
if (!text) return;
if (!cost) return;
totalcost(cost);
}
function totalcost(cost) {
var total = 0;
for (var i = 1; i <= 3; i++) {
var text1 = document.getElementById("name" + i);
if (text1.value != "") total += Number(cost.value);
}
document.getElementById("Total").value = total;
}
I am using jquery to loop through table rows and save the data. If the table has 200 rows it is performing slow. I am getting the javascript message "Stop Running this script" in IE when I call this method. Following is the code I am using to loop through table rows. Can you please let me know if there is a better way to do this.
function SaveData() {
var $table = $('#' + gridid);
var rows = $table.find('tbody > tr').get();
var transactions = [];
var $row, empno, newTransaction, $rowChildren;
$.each(rows, function(index, row) {
$row = $(row);
$rowChildren = $row.children("td");
if ($rowChildren.find("input[id*=hRV]").val() === '1') {
empno = $rowChildren.find("input[id*=tEmpno]").val();
newTransaction = new Array();
newTransaction[0] = company;
newTransaction[1] = $rowChildren.find("input[id*=tEmpno]").val();
newTransaction[2] = $rowChildren.find("input[id*=tPC]").val();
newTransaction[3] = $rowChildren.find("input[id*=hQty]").val();
newTransaction[4] = $rowChildren.find("input[id*=hPR]").val();

newTransaction[13] = $rowChildren.find("input[id*=tL8]").val();
newTransaction[14] = $rowChildren.find("input[id*=tL9]").val();
newTransaction[15] = $rowChildren.find("input[id*=tL10]").val();
newTransaction[16] = $rowChildren.find("input[id*=tSF]").val();
newTransaction[17] = $rowChildren.find("input[id*=tCG]").val();
newTransaction[18] = $rowChildren.find("input[id*=tTF]").val();
newTransaction[19] = $rowChildren.find("input[id*=tWK]").val();
newTransaction[20] = $rowChildren.find("input[id*=tAI]").val();
newTransaction[21] = $rowChildren.find("input[id*=tWC]").val();
newTransaction[22] = $rowChildren.find("input[id*=tPI]").val();
newTransaction[23] = "E";
var record = newTransaction.join(';');
transactions.push(record);
}
});
if (transactions.length > 0) {
var strTransactions = transactions.join('|');
//send data to server
//here ajax function is called to save data.
}
}

Try minimizing your use of jQuery find(). Its performance is really bad on older browsers. Perhaps use good old getElementsByTagName() instead, which is implemented natively even on IE6. Pseudocode:
get list of tr elements;
for each tr element:
get list of input elements descending from current tr element;
for each input:
if input.id matches x
if input.id matches y
if input.id matches z
Hope this helps.
Replace the repeated calls to find by splitting out that part of the id and then doing a var index = $.inArray(idFragment, ['', 'tEmpno', 'hQty']); call or similar strategy to determine the input's position in the transaction array.
Make as few searches on the DOM as possible. Prefer |= over *= selectors if possible.
Or, if possible, modify the serialize function in jQuery as needed and use the index of the input to determine its position in the transaction array.
