JavaScript - Dynamically Inject Multipart Mhtml Content Into Document?

Hello, I am just going through my javascript book and looking/learning at examples. I've copied this code and i'm thinking i could really use this in my site, it's something i've been looking for on the internet for a while.

I have a few questions regarding certain things and I would like to slightly change the code so it performs an additional task.

I have uploaded a live example of the page as it is a lot easier for you guys to help and also easier for myself to explain properly. The file is located he JS test page.

As you can see, you click the different tabs and the relative information comes up.

1)How can I change the code so that if one description is currently on-screen, when another tab is clicked, i want to hide the currently displayed information, and show the relative information to that particular tab.

2)As you can see, clicking the tabs just brings up text saying 'Description for Tab' + #. This is added using the DOM, but i want to add a lot of description and obviously do not want to put an awful lot of text into the function. What is the best way to add this content dynamically? Should I create an XML file and access this file using javascript to display the different information?

I understand question 2 could be done using ajax and php but I know nothing about either so i was wondering if there was another way to achieve this?

Thank you for your time,

Regards,

LC.

Hello All,

I have a code which works fine for what is does but I want to add in dynamically a new list to the Array...... from an input field.

The relevent part of the code reads as this for example........

var step_x_list=new Array("ca1sb2en1pg1itm1","ca1sb2en1pg1itm2","ca1sb2en1pg1itm3")

but I need a way to dynamically replace the existing.... "ca1sb2en1pg1itm1","ca1sb2en1pg1itm2","ca1sb2en1pg1itm3" seen above with a new list from an input field which holds the following say....... ca2sb2en2pg1itm1","ca2sb2en2pg1itm2","ca2sb2en2pg1itm3

I have tried various ideas but none seem to be able to inject the new values in the space between the brackets.

Any thoughts.

Martin.

For those just wondering what the code is and want to try it, it is a one piece code which can fire many different functions without requiring lots of individual bits of code to do same. The action usually happens in micro-seconds but I slowed it to a one second count between changes so you can see what is actually happening.

Below is a revised code if you want to see it working and also to give an idea about the Array part in which I want to add a different number set.
Copy the code and save in notepad as test.html
It can be opened as a web page. Remember to change the code tags to the correct script tags


Code:

var i_x_list=0
function fireFunctionList_x_list()
{
if (document.getElementById("locate_load_x_list").value == "end" || document.getElementById("locate_load_x_list").value == "undefined"){i_x_list=0;document.getElementById("locate_load_x_list").value=""}else{fireFunctionList_x_list_do()}
}
function fireFunctionList_x_list_do()
{
document.getElementById("addto").value="place_";
var step_x_list=new Array("ca1sb2en1pg1itm1","ca1sb2en1pg1itm2","ca1sb2en1pg1itm3","ca1sb2en1pg1itm4","ca1sb2en1pg1itm5","ca1sb2en1pg1itm6","ca1sb2en1pg1itm7",
"ca1sb2en1pg1itm8","ca1sb2en1pg1itm9","ca1sb2en1pg1itm10","ca1sb2en1pg1itm11","ca1sb2en1pg1itm12","ca1sb2en1pg1itm13","ca1sb2en1pg1itm14","end")
document.getElementById('locate_load_x_list').value=step_x_list[i_x_list]
i_x_list=i_x_list+1
document.getElementById("addto").value+=document.getElementById("locate_load_x_list").value;
document.getElementById("final_locate_load_x_list").value=document.getElementById("addto").value;
document.getElementById("final_locate_load_x_list").value+=document.getElementById("addto2").value;
var x_list = document.getElementById("final_locate_load_x_list").value;
setTimeout("fireFunctionList_x_list()",1000)
var f_x_list = new Function(x_list); f_x_list();
}

<BR><BR>
<button onclick="fireFunctionList_x_list()">run the function list rotation</button>
<BR><BR>
<input id="addto" type="text" size=25 value="place_"><BR>
<input id="addto2" type="text" size=4 value="()"><BR>
<input id="locate_load_x_list" type="text" size=20 value=""><BR>
the code fires this function if there<input id="final_locate_load_x_list" type="text" size=25 value=""><BR>
Code:

 function place_ca1sb2en1pg1itm4(){alert("ca1 number4 function dummy run as alert");}

Code:

 function place_ca1sb2en1pg1itm9(){alert("ca1 number9 function dummy run as alert");}

Code:

 function place_ca2sb2en1pg1itm6(){alert("ca2 number6 function dummy run as alert");}

Code:

 function place_ca2sb2en1pg1itm12(){alert("ca2 number12 function dummy run as alert");}

Hi all


I just found this code which isn't mine lurking on one of my pages ---- any idea what it does exactly?



Code:

<script type = "text/javascript">
function OneWay(S) {
var pageName, j, x, y = 2e50;
x = '0.'+ parseInt(S.value, 36);   // 36 is the radix
with (Math) { for (j=0; j<10; j++) x = tan(1+x+x*y%1)%1 }
pageName = ((x+1)/2).toString(36).substring(2);
pageName = pageName + '.html';
alert (pageName);  // for testing - pageName = "xvmrv5eoae0b.html"  when password is "x"
window.location.href = pageName;
}
</script>

Hi ,

I am new to javascript and have coded an invoice page through help from some available content on web.

here is my requirement

My form contains inputs "item ,rate quantity,price" in a tabular form where one can dynamically add or delete rows.And the requirement is that

when Quantity is entered the Price should change to Price=Quantity*Rate on tab out

So I have used a Javascript onchange() and this works fine for the first displayed row. but for dynamically added rows this does not happen, I am not able change the price value for dynamically added rows.

Code is as below
direct_invoice.html

The below is the javascript function that i wrote


Code:

function addRow()
     {
          // grab the element, i.e. the table your editing, in this we're calling it 
          // 'mySampleTable' and it is reffered to in the table further down on the page

Hi,

Is there a way to print (sending to printer) the partial contents within the HTML file
Ex: Can i print content of div2 only?.


<html>
<body>
<div id='div1'>
....
</div>
<div id='div2'>
....
</div>
</body>
</html>

Can you please let me know your inputs. Thanks..
