A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive

[Problem description]

On the page containing Ajax, call the data layer method to update the database. The content of a field is long and contains more than 0.1 million characters.

The access process uses htmlencode and htmldecode.

The problem is:

1. If you enter more than 0.1 million characters or more than 0.2 million characters, the system runs normally.

2. Copy a section with special characters such as ";/span & gt; & lt;/P & gt; & lt; P class = msonormal", in special format, htmlCode, JavaScript code, Web. config file configuration section:

(A) when the number of words is small (about 10 thousand words), it runs normally.

(B) When there are many words (more than 50 thousand words), the following error message is displayed:

After an error message is displayed, the webpage function becomes invalid, and clicking the button on the page does not respond.

I followed up and found that the pop-up of the error dialog box was completed on the server side, while the Ajax endrequest event was not triggered yet.

I tried the following methods:

1. server. scripttimeout = 20. No.

2. Modify executiontimeout in server. scripttimeout and web. config to a smaller value. No.

3. htmlencode and htmldecode are not required.

 

What the hell is going on? How can this problem be solved?

Don't tell me not to enter those characters. All the characters must be input.

Please advise. Thank you.

 

[Solution]

Do it yourself:

It turns out that when there is a lot of data in a DIV, when the DIV value is changed through the control on the page, the operation will be slow or this prompt will appear.

So my solution is:

When a request occurs for the control that triggers this Div change, first clear or set the DIV value to a very simple value, such as "processing ...", Then, the value is assigned back at the end of the request.

This is easily implemented through initializerequest and endrequest of pagerequestmanager in Ajax.
