I am looking to create a button at the bottom of a form that will create an alert box that will show the form data entered. Form includes:
First Name
Last Name
Address 1
Address 2
City
State
Zip
Phone
Fax
Once the form is completed, the button is clicked and an alert box pops up showing the form data entered.
Does anyone know how to accomplish without the form actually being submitted or validated? There is no database for the form data to be submitted to, so there is no database to pull the information from.
Any help would be greatly appreciated.
I have not included the form code due to its length, but the current code I am working with for the Alert Box looks like this:
<script>
function display_alert()
{
alert("");
}
</script>
<body>
<input type="button" onclick="display_alert()" value="Display alert box">
</body>
If I get it right you need something like this:
<html>
<head>
<script type="text/javascript">
window.onload = function(){
document.getElementById('send').onclick = function(e){
alert(document.getElementById("name").value);
return false;
}
}
</script>
</head>
<body>
<form method="post">
<input type="text" name="name" id="name" />
<input type="submit" name="send" id="send" value="send" />
</form>
</body>
</html>
I don't really get what you mean with a database to pull the information from, but the example uses a click event to get the data from the form field and shows it in an alert without a submit.
html code:
<html>
<SCRIPT SRC="PR8_4.JS"></SCRIPT>
<body>
<form name=details>
<table>
<tr><td>ENTER FRIST NAME:<input type=text name=fname></td></tr>
<tr><td>ENTER LAST NAME:<input type=text name=lname></td></tr>
<tr><td>ENTER PHONE NUM :<input type=text name=phnum></td></tr>
</table>
<input type="button" value="Click Me" onclick="display();">
</form>
</body>
</html>
javascript code:
function display()
{
var x=document.details.fname.value;
var y=document.details.lname.value;
var z=document.details.phnum.value;
alert("FIRST NAME:"+x+" "+"LAST NAME:"+y+" "+"PHONE NUMBER:"+z);
}
To stop a form submitting you can create an onsubmit event within the tag and return false - e.g. ...form elements.... This has the benefit of working when someone submits the form by pressing the enter key as well as pressing the submit button.
Thus, to achieve what you desire you could create a function (lets call it formAlert) and call it from the onsubmit event e.g. ...form elements...
The formAlert function would look something like:
function formAlert() {
alert_string = '';
alert_string = alert_string + document.getElementById('first_name').value;
alert_string = alert_string + ' ';
alert_string = alert_string + document.getElementById('last_name').value;
alert(alert_string);
}
and this would correspond to a form looking like:
<form id="foo" onsubmit="formAlert(); return false;">
<p><label for="first_name">First Name<label><input type="text" id="first_name" value="fred" /></p>
<p><label for="last_name">Last Name<label><input type="text" id="last_name" value="blogs" /></p>
<p><input type="submit" value="click me" /></p>
</form>
Note1, this won't be a pretty modal box - it'll simply display "fred blogs" in a Javascript alert box.
Note2, if there is a Javascript error your form will still submit (although in the example here it'll submit to itself).
Here is a JS Fiddle demonstrating the above code: http://jsfiddle.net/D59su/
