Re: What's the difference between an apple and an orange?

One creates an element. The other parses a text representation of a HTML fragment and inserts it in place of an element's current children.

One lets you create elements in a clear, controlled, and generally verbose fashion. The other allows / requires you to create a string representation of what you want.

One is an existing standard[^]. The other is a proposed standard[^] (based on a common - but non-standard - implementation).

In practice, which one you should use really depends on what you're trying to do...

Thank you

is it considered bad practice to use the .innerHTML method because using the document.createElement() method would require a lot of code as lots of elements are created, all with different styles etc.

It really does depend on what you're doing. innerHTML is rather widely supported, so if you need it i wouldn't worry about using it. It can be cleaner and faster than trying to build a large or complicated DOM fragment using other methods. It can also degenerate into a mess of string manipulation complete with subtle errors that only show up on certain browsers due to the various methods used to "correct" invalid HTML.

Hi All,
I am looking for some advice/direction on software documentation, i work as the only developer in a very small company, its my first job after college so i have no real documentation experience and the company is new so basically there is none at the moment. I am developing a web app using C#, ASP.Net, VS2008 and SQL Server 2005 and have spent the last week trying to find info on where to start but no luck, so im just wondering if anyone could give me some advice or point me in the direction of some examples or anything really.

Thanks in advance
Tim

I can't understand how that could happen unless you explain "how" you have been trying.

Where to start is a tough ambiguous problem. As a wild guess where a good place for "you" to start, I would offer this[^]. It has a link to a PDF so I assume you will have no problem viewing the document.

Any future questions about documentation or process should probably go in the General Discussion forum.

If you're wondering why your question got marked down it's probably because of essay-sized title and ugly code-dump.

Without paying any attention to your code or what you are trying to do, the error message tells you everything you need to know. On line 40 of the code (whichever that is, I'm not figuring it out from here) something is trying to access the 'cat' element of an array. This element doesn't exist, hence the error.

1) Then there's your problem.
2) Wrong forum. This isn't web dev, it's an MDAC or ASP issue.

That's a bit of an odd UI, but... eh, whatever.

// 
// adds new method to jQuery, only operates on select lists, adds option with specified text, optional value
//
$.fn.addOption = function(optText, optVal)
{
   this.filter("select").each(function()
   {
     var opt = new Option(optText, optVal);
     this.options.add(opt);
   });
}

//
// attaches to blur event of input field with id of textentry, 
// causes it to add text to select list with id of dropdown (if text is non-empty / non-whitespace)
//
$(function()
{
   $("#textentry").blur(function() 
   {
      var optionText = $.trim(this.value);
      this.value = '';
      if ( optionText.length > 0 )
         $("#dropdown").addOption(optionText);
   });
});

Thank you Shog for ur kind response first!! Rose | [Rose]

Can u able to give me an example for that to use that jquery and I don't know how to pass the value to the function, and the function seems to be we have to pass the value of both the name and id. is it?

For me the task is that we have to already defined the names for the corresponding numbers like 1=name1, 2=name2,

I want to add the name in drop down when I just press 1 in textbox

Waiting for ur response.

Shog⁹30-Jul-08 8:18

Well, obviously i don't know how you're obtaining IDs or associating names with them, but you could try something like this:

// 
// adds new method to jQuery, only operates on select lists, adds option with specified text, optional value
//
$.fn.addOption = function(optText, optVal)
{
   this.filter("select").each(function()
   {
     var opt = new Option(optText, optVal);
     this.options.add(opt);
   });
}

var mapIdToName = 
{
   1 : "name1",
   2 : "name2",
   3 : "name3",
   4 : "George",
   5 : "name5"
};

//
// attaches to blur event of input field with id of textentry, 
// causes it to add text to select list with id of dropdown (if text is non-empty / non-whitespace)
//
$(function()
{
   $("#textentry").blur(function() 
   {
      var optionVal = $.trim(this.value);
      var optionText = mapIdToName[optionVal];
      this.value = '';
      if ( optionText )
         $("#dropdown").addOption(optionText, optionVal);
   });
});

Something just occurred to me: are you trying to implement an auto-complete / filter system? If so, you should probably check out this: http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/[^] (soon to be a part of the official jquery.ui suite).

To create web application without the knowledge of programming? Sounds mission impossible.

But with http://www.finereport.com/, it is possible.

On the Excel like workbook, user just need to drag and draw Element (data field, chart, links) to cell, and set the format and editable of the cell, plus the access control, you can turn the template to a web report or a form.

So web application without coding is very possible.
