Calculate my amount

Dynamically calculates from my text box

[Shuvi]

Does some one know a JS that I can use that takes the values a user enters for totals the amount at the bottom. I have five possible text boxes user can enter values into. I would like to see the total as they enter.
Any help is appreciated!

I think you will need to call a calculating function in the onblur event handler of the text box.

<input type="text" onblur="calculate()" id="textbox1">

Can you give me more details? Please?

[korkus2000]

here is a basic script you could modify

<script>
function calculate(){
if(isNaN(document.test.textbox1.value) ¦¦ document.test.textbox1.value==""){
var text1 = 0;
}else{
var text1 = parseInt(document.test.textbox1.value);
}
if(isNaN(document.test.textbox2.value) ¦¦ document.test.textbox2.value==""){
var text2 = 0;
}else{
var text2 = parseInt(document.test.textbox2.value);
}
if(isNaN(document.test.textbox3.value) ¦¦ document.test.textbox3.value==""){
var text3 = 0;
}else{
var text3 = parseInt(document.test.textbox3.value);
}
if(isNaN(document.test.textbox4.value) ¦¦ document.test.textbox4.value==""){
var text4 = 0;
}else{
var text4 = parseInt(document.test.textbox4.value);
}
document.test.textbox5.value = (text1+text2+text3+text4);
}
</script>
<form name="test">
<input type="text" onblur="calculate()" name="textbox1"> <br>
<input type="text" onblur="calculate()" name="textbox2"><br>
<input type="text" onblur="calculate()" name="textbox3"><br>
<input type="text" onblur="calculate()" name="textbox4"><br>
<br>
answer<br>
<input type="text" name="textbox5"><br>
</form>

Change the broken pipe characters to regular pipe characters. It will not see these as or and will throw exceptions.

Thank you!

I tried this but it's not working. At the botton in the status bar it's giving me a exclamation for error.
Not sure what is going on.

Double click on the exclaimation error icon... what does it tell you in the box that appears, exactly?

[Shuvi]

My mistake. It's fixed!
Thank you. But I didn't know that if you double click the exclamation it would tell you the error. Thanks for the tip!

I just noticed that it doesn't calculate decimal places. Can anyone help?

[Shuvi]

Nevermind I just changed it to ParseFloat.
Ignore my last entry.

[Shuvi]

Is there a way to limit the number of decimal places it goes till? Is there anything called ParseCurrency?

Shuvi,

This was just addressed in this group a couple of days ago. Here is a link to the thread--two alternate answers can be found in #6 and #7.
