Menu
I have the following html which displays 3 textboxes and an add button:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div id="container">
<div id="line-item">
<asp:TextBox ID="txtLineNumber" runat="server"></asp:TextBox>
<asp:TextBox ID="txtQty" runat="server"></asp:TextBox>
<asp:TextBox ID="txtItemCode" runat="server"></asp:TextBox>
<asp:ImageButton ID="imgBtnAddNewLineItem" ImageUrl="~/images/add_button.jpg"
runat="server" />
</div>
</div>
</form>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2
/jquery.min.js">
</script>
<script src="js/invoice.js" type="text/javascript"></script>
</body>
</html>
When the user clicks the add button, I want to create another div with the line-item id and put it on the next line. I created a js file, but I am not sure how to do it?
Here is what I have so far:
var itemCount = 0;
function getLineItem(number) {
var div = document.createElement('div');
$(div).attr("id", "lineitem" + number);
var t1 = getTextbox("txt" + number.toString() + "1");
var t2 = getTextbox("txt" + number.toString() + "2");
var t3 = getTextbox("txt" + number.toString() + "3");
$(div).append(t1);
$(div).append(t2);
$(div).append(t3);
return $(div);
}
function getTextbox(id) {
var textbox = document.createElement('input');
$(textbox).attr("id", id);
return $(textbox);
}
var lineItemCount = 0;
$('#imgBtnAddNewLineItem').click(function() {
lineItemCount++;
$('#line-item').clone().attr('id',getLineItem(lineItemCount)).appendTo('#container');
});
});
804
$(document).ready(function() {
$('#imgBtnAddNewLineItem').click(function() {
$('#container').append('<div></div>');
});
});
Update 2
Create a normal button like so:
<input type="button" id="imgBtnAddNewLineItem" value="Add lineitem" />
Update ** This is also updated with comments etc.. **
//Count the lineItems to make sure they are unique
var lineItemCount = 0;
//On document ready
$(document).ready(function() {
//On button click
$('#imgBtnAddNewLineItem').click(function(e) {
/*
ADD THE FOLLOWING LINE TO PREVENT THE POSTBACK
P.S. - Make sure you pass -e- to this function...
*/
e.preventDefault();
//Increase the lineitemcount
lineItemCount++;
//Add a new lineitem to the container, pass the lineItemCount to make sure getLineItem() can generate a unique lineItem with unique Textbox ids
$(container).append(getLineItem(lineItemCount));
});
});
//Create a new DIV with Textboxes
function getLineItem(number) {
var div = document.createElement('div');
//Give the div a unique id
div.setAttribute('id','lineitem_' + number);
//pass unique values to the getTextbox() function
var t1 = getTextbox('txt_' + number + '_1');
var t2 = getTextbox('txt_' + number + '_2');
var t3 = getTextbox('txt_' + number + '_3');
div.appendChild(t1);
div.appendChild(t2);
div.appendChild(t3);
return div;
}
//Create a textbox, make sure the id passed to this function is unique...
function getTextbox(id) {
var textbox = document.createElement('input');
textbox.setAttribute('id',id);
textbox.setAttribute('name',id);
return textbox;
}
