1. javascript Exception Handling Mechanism

Throw str

Not throw error .. cause ie, ff error obj is diff ..

 

2. unified handling of Web Front and back-end exceptions

If no java exception is converted to a js exception, go to OK...

Dwr has seen abnormal conversion of dwr. 3. It does not take effect... so we have to output str for conversion...

ElmtC. fileChangeEvent ($ ("# filePath"). val (), function (data)

{

ProcessJavaEX (data );

Var plt_s = secs2str (data. Duration );

$ ('# Playtime'). timespinner ('setvalue', plt_s );

 

 

});

If (NoSetAwd (activityId )){

RuntimeException e = new RuntimeException ("e: noSetAwdErr no prize set for this activity .");

String s = JSONObject. toJSONString (e );

Return s;

}

 

// {"@ Type": "java. lang. runtimeException "," localizedMessage ":" e: noSetAwdErr no prizes have been set for this activity. "," message ":" e: noSetAwdErr. No prize has been set for this activity. "," stackTrace ": [{" className ":" com. focustar. servlet. awardServlet "," fileName ":" AwardServlet. java "," lineNumber ": 132," methodName ":" main "," nativeMethod ": false}]," suppressed ": []}

 

Function logx (msg ){

Try {

Console.info ("---------- from logx ");

Console.info ("--" + msg );

} Catch (e ){

// Not support console method (ex: IE)

}

}

Function processJavaEX (data)

{

If (typeof data = "string ")

Data = eval ("(" + data + ")");

If (data ["@ type"]! = Null & data ["@ type"] = "java. lang. RuntimeException ")

{

If (data. message! = Null)

Logx (data. message );

Throw data. message;

}

If (data ["stackTrace"]! = Null)

{

If (data. message! = Null)

Logx (data. message );

Throw data. message;
