How To Change Option Tag Values With Prompt Window Inputs...

Similar Tutorials

View Content

I am working on an interest and investment calculator for a class project. On my list of drop down options, one of the options isnt an integer value like the rest. It's value is "other", while the other three are 1000, 5000, 1000, and 25000. What I would like to do is when the user chooses the "other amount" option from the drop down list, a prompt window will come up asking the user for an investment amount. I am having problems creating a function in my javascript file for this, and then taking the value entered and assigning a variable in another function with that new value so that it calculates with the users input. Please help. The first part of the attachment is the label with the "other" value I explained. And the second piece of code is my mess of a function that I tried to create for the prompt window to come up and store the users value and then change the value of the option. I'm new at this and am lost.....

This is in my HTML:

<label for="investment">One-Time Investment:</label>
<select name="investment" id="investment"
<optgroup label="">
<option value="1000">$1,000</option>
<option value="5000">$5,000</option>
<option value="10000">$10,000</option>
<option value="25000">$25,000</option>
<option value="other" >Other value</option>
</optgroup>
</select><br />

This is in my javascript file:

var show_prompt = function() {

if ($("other").checked ==true){
var number = prompt("please enter an investment amount", "1000");
var numb = parseFloat(number);
$("other").value = numb;
}else{
alert("Please enter your investment amount");
}
return numb;

}

Validating The Sum Of Two Inputs

Hi Folks

I am trying to write a js that validates a form with two text inputs. The two inputs a 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100."

I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work. I would very much appreciate any suggestions!

Thanks! The html code for my very simple form is:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
</head>

<body>
<form id="form1" name="form1" method="post" action="">
<label>Investment in Tech A
<input name="D_techA" type="text" id="D_techA" />
</label>
<label>Investment in Tech B
<input name="D_techB" type="text" id="D_techB" />
</label>
<p>
<input name="Submit" type="submit"/>
</p>
</form>

Need To Run Js In Ie And Not Get The Security Prompt

View Content

I'm working on an html form that will be launched from within another application, but every time it launches the form none of the JS coding works because of the stupid IE security. If I launch the form from outside the application I just have to select "allow blocked content" from that stupid information bar that says "to help protect your security IE has restricted the webpage from running scripts...."

I added the application site to our trusted sites and basically turned off security for that zone but it still doesn't work. Obviously there is a way to run JS without allowing the content, but I don't do enough coding to know how that is done.

Can someone help me out please? I need the JS to run automatically without that information bar appearing at all.

Prompt Within Loops?

I've been asked to create a program which allows meteorologists to input a certain amount of data inputs of snowfall, and then the individual snowfall of each input itself.

In my mind this should prompt me for a data input as many times as their are inputs, however, it works only for the first data input, then it returns to blank page without prompts for the second input...

Any clues as to where I'm going wrong?

When you do an alert confirm you can make if statements to say if they click ok do this and if they click cancel stop the program. Well I am trying to make a prompt that first asks the user to enter in a url and after they do and click enter they url is wraped with img tags.

I would like to make it so that if the user clicks cancel the program ends b/c right now if the user click okay with no value the result is [img][/img] and if the user clicks cancel the result is [img]null[/img]. Any step in the right direction would be greatly appreciated!

PHP Code:
<script language="javascript">
  function imgGenerator(){
      var question=confirm("Would you like to share an image?");
      if (question==true){
         var obj=document.getElementById("mngl-board-post-input");
         var imgurl = prompt("To Share an image paste the image url here");
         var txt=document.createTextNode("[img]"+imgurl+"[/img]");
         obj.appendChild(txt);
      }
      else {}
  }

Javascript - New Array Via Prompt

Similar Tutorials

View Content

I am new to learning JS and am trying to create an array through a prompt. It seems to work, but I believe it is treating the prompted numbers as strings not numbers. I am parsing the negatives and zeros, and positives and counting them. It doesn't recognize the negative sign.

Here's my js:

function counter()
{
var numArr = new Array(Number(prompt("Please enter and array of numbers, in any order, separated by a comma..." + '\n' +
"In the following format: -2,0,2")));

var positives = 0;
var negatives = 0;
var zeros = 0;

for (var i = 0; i < numArr.length; i++)
{
switch (true) {

case numArr[i] < 0:
negatives++;
break;
case numArr[i] == 0:
zeros++;
break;
case numArr[i] > 0:
positives++;
break;
}
}
alert("You entered:"+ '\n' +
"Number of Negatives: " + negatives + '\n' +
"Number of Zeros: " + zeros + '\n' +
"Number of Positives: " + positives);
}
counter();

Any suggestions?

Using A Prompt Box To Execute A .php Function.

Im alright with .php but not good at javascript at all.

this is the javascript code placed in the head tags of my page

var answer = confirm("Delete news item?")
if (answer){
window.location = "main.php?id=delete&note="+noteID+"&status=delete";
}
else{

this is the .php that links to the javascript function
PHP Code:
if($this->admin){

                         .'<a href="" onclick="confirmation('.$row['noteID'].')" class="grey">[Delete]</a>'; }

this is the .php code that executes if the url is status=delete
PHP Code:
                    // This displays if id = Delete A News & user=ADMIN
                    if( $id == "delete" && $session->isAdmin() ) {

                        }

this line in the third code snippet works perfect:
" PHP Code:
<a href="?id=delete&note={$noteID}&status=delete">Yes</a>

"

I'm having great difficulty for the "window.location =...... " to navigate to the right url. It doesn't include the noteID which enables me to delete news items.

Any help would be greatly apreciated (:
