javascript - can't set input value using jquery -


मेरे पास निम्न चिह्न है: 

  & lt; i class = "fa चेक-डेट एफए-चेक-सर्कल-ओ "डेटा-एबीआईटीए-डेट =" 1 "डेटा-तारीख-मूल्य =" 250.00 "& gt; & lt; / i & gt;

और निम्न इनपुट: 

  & lt; इनपुट प्रकार = "टेक्स्ट" id = "convo-abierta" name = "convo-abierta" value = "" & gt;

मैं निम्नलिखित jquery का उपयोग करके एक इनपुट के मूल्य को सेट करने का प्रयास कर रहा हूं: 

  $ ("चेक-डेट")। क्लिक करें (फ़ंक्शन () AddClass ('fa-circle-thin'); $ (यह) .toggleClass ('fa-circle-thin fa- चेक-सर्कल- o '); $ ("# convo-abierta")। Val ($ (यह) .डेटा ("अबाउट-डेट"));});

लेकिन इनपुट का मान हमेशा खाली होता है मैंने इस कोड की कोशिश की: 

  अलर्ट ($ (यह) .डेटा ("अबाउट-डेट"));

और मान प्राप्त करें, लेकिन मुझे समझ में नहीं आ रहा है कि मैं अपने इनपुट फ़ील्ड में मान क्यों सेट नहीं कर सकता। 

  $ ("# convo-abierta" ) .attr ('value', $ (this) .data ("abierta-date"));
