Trouble taking two user chosen inputs and doing calculation - javascript

My html code to take two user chosen input numbers and do calculation. Trouble having it actually do calculation after user chooses inputs. When I put in the two numbers and push calculate it doesnt do anything.
function calc(form)
{
if(isNaN(form.resistance.value))
{
alert("Error in input");
return false;
}
if(form.resistance.value.length > 32)
{
alert("Error in input");
return false;
}
function calc(form1)
{
if(isNaN(form1.strain.value))
{
alert("Error in input");
return false;
}
if(form1.strain.value.length > 32)
{
alert("Error in input");
return false;
}
var Rchange = 2 * form1.strain.value * form.resistance.value;
var newResistance =(parseInt(form.resistance.value) + Rchange);
document.getElementById("newResistance").innerHTML = chopTo4(newResistance);
}
function chopTo4(raw)
{
strRaw = raw.toString();
if(strRaw.length - strRaw.indexOf("0") > 4)
strRaw = strRaw.substring(0,strRaw.indexOf("0") + 5);
return strRaw;
}
</script>
</head>

How to increment the two text box values when button is clicked?

jQuery(document).ready(function() {
// This button will increment the value
$('.qtyplus').click(function(e) {
e.preventDefault();
fieldName = $(this).attr('field');
//alert(fieldName);
var currentVal = parseInt($('input[name=' + fieldName + ']').val());
if (!isNaN(currentVal)) {
$('input[name=' + fieldName + ']').val(currentVal + 1000);
} else {
$('input[name=' + fieldName + ']').val(1000);
}
});
});
function buttonClick() {
//alert("hi");
var n = document.getElementById('rs').value;
alert(n);
var i = 50;
if (i == 50) {
alert(i);
var n = +n + +i;
alert(n);
}
}

<h3> Calculator</h3>
<table style="width: 30%;">
<form name="calc" action="" method="post">
<tr>
</tr>
<tr>
<td>quantity:</td>
<td><input type="text" name="value1" /></td>
</tr>
<tr>
<td>price:</td>

<td>discount:</td>
<td><input type='text' name='rs' value='500' field='rs' id='rs' class='counter' onclick="buttonClick()" /></td>
</tr>
<tr>
</tr>
</form>
</table>
In above HTML code, when button is clicked, I have to increment the two text box values
For example, click a button, price text box value will be 3000, discount text box value will be 550
price text box value is incremented, but discount value will not be changed.
Second script are run,but the text box value are not changed.
You just forget to change the value of the discount input.
<script type="text/javascript">//second script
function buttonClick() {
//alert("hi");
var n = document.getElementById('rs').value;
alert(n);
var i = 50;
if (i == 50) {
alert(i);
var n = +n + +i;
alert(n);
$("#rs").val(n) // add this line
}
}
</script>
You have not written anything to change value of discount textbox.
you can do as follows:
$('.qtyplus').click(function (e) {
e.preventDefault();
qty = $('.qty').val();
discount = $('#rs').val();
var currentQtyVal = parseInt(qty);
if (!isNaN(currentQtyVal)) {
$('input[name=quantity]').val(currentQtyVal + 1000);
} else {
$('input[name=quantity]').val(1000);
}
var currentDiscountVal = parseInt(discount);
if (!isNaN(currentDiscountVal)) {
$('input[name=rs]').val(currentDiscountVal + 50);
} else {
$('input[name=rs]').val(50);
}
});

How can i stop to seeing any focus-out() action when i click reset button????
When you reset the form, you are hiding all the error messages. Then focus on the first element - username.
//refresh button action:
$('input[type=reset]').click(function(){
$("#username_error_msg").hide();
$("#gender_Select_error_msg").hide();
$("#jobCategory_error_msg").hide();
$("#experience_sector_error_msg").hide();
$("#password_error_msg").hide();
$("#retype_password_error_msg").hide();
$("#email_error_msg").hide();
$("#phone_no_error_msg").hide();
$("#short_note_error_msg").hide();
$('#username').focus();
});
Blur comes before click so you are setting the .html of the error, then the click comes and you hide it but because you use .slide jQuery will then set it visible again as it's sliding in.
The simplest way would be to set the html of the error to an empty string, jQuery can then slide in an empty string:
function removeErrors(){
$("#username_error_msg").html("");
$("#gender_Select_error_msg").html("");
$("#jobCategory_error_msg").html("");
$("#experience_sector_error_msg").html("");
$("#password_error_msg").html("");
$("#retype_password_error_msg").html("");
$("#email_error_msg").html("");
$("#phone_no_error_msg").html("");
$("#short_note_error_msg").html("");
}
//refresh button action:
$('input[type=reset]').click(function(){
removeErrors();
});

form validation javascript (error message showed and disappeared quickly)

i want to show the error messages next to the input element and if there's no error messages then send the data to the server (clear data from form) so fire the function on submit
http://codepen.io/anon/pen/RPNpNw
the problem is the error messages showed and disappeared quickly (blink)
but when change the input type to button
http://codepen.io/anon/pen/EjaZqe
will work but the data will be still in form and not cleared as input type="submit" will do
<!DOCTYPE html>

document.getElementById('errorage').style.color = 'red';
return false;
}
else {
document.getElementById('errorage').innerText = ('');
return true;
}
}
function checkuser(input) {
var pattern = '^[a-zA-Z]+$';
if (input.value.match(pattern)) {
document.getElementById('erroruser').innerText = '';
return true;

</html>
Change
<td><input type="submit" value="register" onclick="allvalidate()" /></td>
To:
<td><input type="submit" value="register" onclick="return allvalidate()" /></td>
Otherwise the boolean value is discarded. You also need to change allvalidate to actually return false if one of the validations fail:
function allvalidate() {
var validated = true;
if (!validate()) validated = false;
if (!checkAge(txtage)) validated = false;
if (!checkuser(txtuser)) validated = false;
if (!checkSelect(this)) validated = false;
return validated;
}
<tr>
<td></td>
<td><input type="submit" value="register" onclick="allvalidate()" /></td>
</tr>
well, I'm not expert but what I think is that data is not sending, you need to call the function on onsubmit event, instead of calling it on onclick event. It would send the data as well.

I want to change color in the movement cell according to the data. If the the current value is lower than the preceding value I want it to be red and if the current value is more than the preceding value than I want it to be green. I believe it requires a minor change in the "movement function"
Please help.
Here is a jsfiddle for the scenario: Click Here
Is this not what already happens. I have tested the jsfiddle (http://jsfiddle.net/4QBwK/), behaviour seems a little odd, but I think it fits what you have specified.
The only change I think is needed is to remove most of the code from the format_cell() function that seems to randomly light up cells in either red or green. I have commented it out on this jsfiddle: http://jsfiddle.net/4QBwK/1/
So you would just have this instead:
function format_cell(row, col, pre_value)
{
calculate_grid();
}
