[ZT] Customer Service htmldecode and htmlencode-in Javascript

Source: Internet

Today, I encountered a problem. To implement paging through Ajax, we need to return the htmlCodeEnd re-assembly, one is paging, and the other is the query result. In this case, how can we separate the code at both ends? The method I came up with was to construct a JavaScript Object in the ajaxmethod and add the two pieces of code to the object's property value.

" // Construct JavaScript Object
VaR Objhtml =   New Object ();
Objhtml. firstsection =   ?;
Objhtml. secondsection =   ?;
"

Then, construct the returned JavaScript Object through eval (strcode) in the front-end callback function. Then, it is very easy to update the corresponding HTML block.
I can replace the question mark in the above Code with two HTML code block strings, but I want to decode the front-end if I add encode to them, I tried to add the server in the background. urlencode (strhtml), the foreground needs to set uridecode () and unecape (), but the space inside is still '+', adding a Replace (/\ +/g ,'') you can solve it. The potential problem is that if there is '+' in the content, there will be a problem. So I searched the internet to see if there is any better solution, the result shows that a clever method is implemented using containers in HTML.
Javascript htmlencode implementation : Function Htmlencode (strhtml)
{
VaRDiv=Document. createelement ('Div');
Div. innertext=Strhtml;
ReturnDiv. innerhtml;
}

Javascript htmldecode implementation : Function Htmldecode (strencodehtml)
{
VaRDiv=Document. createelement ('Div');
Div. innerhtml=Strencodehtml;
ReturnDiv. innertext;
}

This implementation is convenient and simple. The following is the sample code for your reference. < Script Type = " Text/JavaScript " >
Function Htmlencode (strhtml)
{
VaRDiv=Document. createelement ('Div');
Div. innertext=Strhtml;
ReturnDiv. innerhtml;
}
Function Htmldecode (strencodehtml)
{
VaRDiv=Document. createelement ('Div');
Div. innerhtml=Strencodehtml;
ReturnDiv. innertext;
}
Function Test1 ()
{
VaR Strinput = Prompt ( ' Test htmlencode (), Please input decodehtml ' , '

5
' );
Alert (htmlencode (strinput ));
}
Function Test2 ()
{
VaR Strinput = Prompt ( ' Test htmldecode (), Please input encodehtml ' , ' & lt; Div style = "width: 600px;" & gt; & lt; input type = "button" name = "runstart" value = "View" onclick = "Run ()" style = "margin-left: 2px;" & gt; & lt; input type = "button" name = "runstart" value = "runscript" onclick = "runscript ()" style = "margin-left: 10px;" & gt; & lt; input type = "button" name = "reset" value = "clear" onclick = "RESET ()" style = "margin-left: 18px;" & gt; & lt; SPAN onclick = "expandcollapse (this);" onmouseover = "showmsg ();" onmouseout = "hidemsg ();" MSG = "Expand" style = "font-family: webdings; font-size: 18pt; cursor: pointer; "& gt; 5 & lt;/span & gt; & lt;/Div & gt; & lt; IFRAME name = "ifrshow" style = "margin: 0px; margin: 0px; width: 600px; Height: 400px; Border: 1px orange solid;" & gt; & lt; /iframe & gt; & lt; Div id = "divmsg" style = "display: none" & gt; & lt;/Div & gt; ' );
Alert (htmldecode (strinput ));
}
< / SCRIPT> <button onclick = "test1 ();"> test htmlencode < / Button >
< Button onclick = " Test2 (); " > Test htmldecode < / Button>
