Javascript - Calculate The Bytes Of Text In A TextArea?

Aug 29, 2010

I need to find a way to accurately calculate the byte size of the text inside a particular textarea. I am working in .Net so I have access to those libraries, but I'd prefer a Javascript solution. How many bytes is each character worth? What would be the most efficient way to count and multiply? Or am I missing a better way entirely?

Edit: I'm attempting to determine the download size of a piece of Javascript that has been pasted into a textarea. The closest thing I could find to this is ][URL]. I don't want to just lift their code, especially since I don't fully understand it.

MVC :: Html.TextArea - Extra Line Break In The TextArea, Just Above The Original Text?

Jul 15, 2010

I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.

I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.

On the second page, I render a TextArea with this search input text from the ViewData.



The problem is, there is an extra line break in the TextArea, just above the original text.

Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.

This can be repeated - every time the page reloads it has another line break.

It's driving me insane - does anyone have an idea on how to fix this?

FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.

MVC - Change The Value Of The Text In The Textarea?

Jul 12, 2010

I have a WYSIWYG editor set up using ASP.NET MVC. When I post, everything is fine, however when I post and there is an error when the page comes back and shows the errors, the value in the textbox is messed up (it has become un-HTML Encoded) and for form validation reasons, this is fine. My question is this - how, in the controller (preferably), can I change the value of the text in the textarea? Even if I use a ViewData["fieldname"] and set the asp code to:

<%= Html.TextArea("fieldname", ViewData["fieldname"], new { id = "fieldthing", name = "fieldthing", cols = "80", rows = "10" })%>

It still doesn't work because that ViewData is the default value which, after the post, isn't returned to that value, it stays whatever was typed.

So any thoughts on how to edit this value? I tried passing in a new view, but that didn't work either.

Access Textarea's Value Through Javascript In .NET?

Nov 9, 2010

I have a textarea and i am using a plugin for that textarea. In that plugin there is a function getCode() which will return the value of the textarea. That function will be called like - textarea_id.getCode(); I am using ASP.NET in which i have declared the textarea (runat=server), and the textarea'a id i can get but when i am writing the following code it is not calling the method.

'<%= txtName.ClientID %>'.getCode();

But if i am writing then it is working fine.


Because the first one is a string and the second one i guess is an object. If so then how to overcome this problem.

Code Block

Plugin = function(obj)
var self = document.createElement('iframe');[code]....

Convert Textarea Text Into Valid HTML?

Mar 4, 2010

there are a few paragraphs separated by line feeds "

" in a textarea, say

Paragraph1 "
Paragraph2 "
Paragraph3 "

what i want to achieve is to process each paragraph into tag. How do you do that? (Need a server side solution) so it looks like

<p> Paragraph 1 </p>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>

On top of the complexity, if you have a blockquote there

Paragraph1 "
<blockquote> "
</blockquote> "
Paragraph2 "
Paragraph3 "

should come out to look like

<p> Paragraph 1 </p>
<p> Paragraph 2 </p>
<p> Paragraph 3 </p>

Javascript - Displaying <textarea> Value As HTML?

Dec 28, 2010

I have a form with several textarea elements. User enters data and submits the form. On the next page it shows submitted text as static text - in p tags. Obviously New Line and multiple paces get ignored and everything just shows in one line. I can do some preprocessing like replacing New line characters with "br/" and spaces with . but I was wondering if there is a standard solution to that either on server side (C#) or client side (javascript)

Calculate Total By Javascript In Gridview With Paging?

May 2, 2010

Without paging function, i can loop through the gridview by using

var sum = 0;
var gridViewCtlId = '<%=timesheetView.ClientID%>';
var grid = document.getElementById(gridViewCtlId);
var gridLength = grid.rows.length;

so with gridLength i can loop through the gridview to sum all rows. However, when I use paging event of gridview, i use the page size to loop through all rows, but it occurs errors because the last page may not have enough rows.

SQL Server :: How To Insert A Large Bytes

Jan 3, 2011

In my program, I need update a filed to the database. The field is for a pdf file content. I know, maybe I should save the pdf file to the local file system, and save the file path to the SQL. but, right now, it is the file content saved to the SQL.

from my program, it loads the file which is input by user. I use File.ReadAllBytes. Then, run the stored procedure on the SQL server, and use the bytes[] as parameter, to insert the file to the SQL. it works fine when file size is small. However, as file size becomes larger, say 200MB, sometimes, it pops out of memory exception.

So, I'm thinking, maybe I can load parts of the file, say 1MB a time, then update the database, then loop. so, this way, no matter how large the file is, it should not have any problem.

my question is: is there a standard way to do this? so, I should not save file content to the SQL at all? shoudl save file in file system, save the file path to sql only? or there are other way to deal with this?

Web Forms :: Read Image Bytes From Database And Display?

Jan 18, 2011

I have a database which signature images. Images are saved in binary.

I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.

The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?

Is there a way to put the stream into a session variable and then point to that as a url?

for instance replacing the last line below with this and then pointo to it from image1.imageurl?
