JQuery: pass $(this).parent(); to method? -

-

मेरे पास एक साधारण स्क्रिप्ट है: 

  $ ('विस्तृत करें')। प्रत्येक ( फ़ंक्शन (i) {var _Expand = $ (यह)। Parent (); ExpGroupBy (_Expand);});

वर्ग के विस्तार के साथ & lt; tr & gt; सभी & lt; td & gt; पास करने की कोशिश कर रहा है

< P> हालांकि, firebug त्रुटि को पॉप अप कर रखता है:

'TypeError: formObj.getElementsByTagName फ़ंक्शन नहीं है'

कोई भी विचार?

< P> धन्यवाद ^^

जब तक फ़ंक्शन समझता है कि पैरामीटर jQuery ऑब्जेक्ट है और नहीं डोम तत्व ही यदि फ़ंक्शन को एक DOM तत्व संदर्भ की अपेक्षा होती है, तो आप आसानी से ऐसा कर सकते हैं ... 

  $ ('विस्तृत करें')। प्रत्येक (फ़ंक्शन (i) {var _Expand = $ (यह ) .पीरेंट (); एक्सपेग्यूफ़ीबी (_Expand [0]); // नोट [0]});

And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
