javascript - Getting undefined for jQuery position variable - 


  $ ("# कैप्चर")। क्लिक करें (फ़ंक्शन (इवेंट) {var photoCoords = $ ("# doge1 ") .position ();})

उपयोगकर्ता को #capture आईडी के साथ कैप्चर बटन पर क्लिक करने के बाद मैं एक तस्वीर के निर्देशांक प्राप्त करने के लिए ऊपर का उपयोग कर रहा हूं छवि में # doge1 का एक आईडी है

जब मैं सांत्वना में var फोटो कॉओर्ड टाइप करता हूं, तो मुझे अपरिभाषित की वापसी मिलती है।

इसकी एक गुंजाइश मुद्दा चर अज्ञात समारोह के बाहर सुलभ नहीं है अगर आपका डिबग करने की कोशिश कर रहा है - आप कंसोल। लॉग स्टेटमेंट को अनाम फ़ंक्शन में भी डाल सकते हैं। अन्यथा आप को वेरिएबल को एक दायरे में घोषित करना होगा जहां यह आपके लॉग स्टेटमेंट के लिए सुलभ होगा। 

  $ ("# कैप्चर")। क्लिक करें (फ़ंक्शन (इवेंट) {var photoCoords = $ ("# doge1")। स्थिति (); console.log (photoCoords);}) < / कोड>
