? 1. [Code] JavaScript code

Function cj_start (depname, groupid ){
VaR URLs = "<% = PATH %>/usergather. Action ";
VaR status = "";
VaR html_1 = "<IFRAME frameborder = \" 0 \ "scrolling = \" NO \ "width = \" 600 \ "Height = \" 60 \ "src = \" <% = basepath %> cj_status.jsp \ "style = \" margin-top: 3px; Vertical-align: middle; \ "> </iframe> ";
$ ("# Cj_status_html" ).html (html_1 );
VaR html_2 = "";
VaR cj_butoon = "";
$. Ajax ({
URL: URLs,
Type: "Post ",
Datatype: "JSON ",
Data: {depname: depname, groupid: groupid },
Success: function (data ){
If (data. cjstatus. length! = 0 ){
If (data. cjstatus [0] = "0 "){
Cj_button = "<input type = \" button \ "value = \" collection channel \ "Disabled = \" disabled \ "/> ";
$ ("# Cj_button_html" ).html (cj_button );
}
For (VAR I = 1; I <data. cjstatus. length; I ++ ){
Html_2 + = data. cjstatus [I] + "";
}
$ ("# Cj_status_html" ).html (html_2 );
} Else {
Html_2 = "Collection System error. Please contact the developer! ";
$ ("# Cj_status_html" ).html (html_2 );
}
}
});

</TD>
</Tr>
<Tr>
<TD id = "cj_status_html">

</TD>
</Tr>
