jquery - How to parse a variable in Javascript -


मैं इस कोड का उपयोग करने की कोशिश कर रहा हूं: 

  var field = "myField"; Vals [x] = document.myForm.field.value;

मेरे पास html कोड है 

  & lt; form name = "myForm" & gt; & Lt; इनपुट प्रकार = 'रेडियो' नाम = 'myField' मान = '123' / & gt; 123 & lt; इनपुट प्रकार = 'रेडियो' नाम = 'मायफिल्ड' मान = 'एक्सआईज' / & gt; Xyz & lt; / form & gt;

लेकिन यह मुझे त्रुटि देता है: 

  document.myForm.field अपरिभाषित है

मैं कैसे प्राप्त कर सकता हूं फ़ील्ड को एक फ़ील्ड के बजाय एक चर के रूप में माना जाना चाहिए?

यह मानते हुए कि आपका अन्य वाक्यविन्यास सही है (मैंने चेक नहीं किया है), यह वह काम करेगा जो आप चाहते हैं: 

  var field = "myField"; Vals [x] = document.myForm [field] .Value;
