javascript - Check two id's on button press -


यह मेरा वर्तमान कोड है: 

  & lt; script & gt; $ ('# रजिस्टर') क्लिक करें (फ़ंक्शन (ई) {if ($ ('$ company_f')। Val ()। लंबाई == 0) {$ ('# company_f')। सीएसएस ("सीमा", " ठोस 1px लाल "); वापसी झूठी; // या e.preventdefault ();}}}; & Lt; / स्क्रिप्ट & gt;

मैं आईडी code_f और telephone_f की जांच के लिए इस कोड को कैसे बदल सकता हूँ? यह वही है जो मैंने कोशिश की है: 

  यदि ($ ('# company_f')। Val ()। लंबाई == 0 या ($ ('# telephone_f')। Val () लंबाई == 0) {   
 
 
  या  ऑपरेटर में जावास्क्रिप्ट दो पाइप है:  || । किसी भी तरह से, यदि आप दोनों स्थितियों को देखना चाहते हैं तो आपको एक AND ऑपरेटर की आवश्यकता है:  & amp;  
 
 < Code> if ($ ('# company_f')। Val ()। लंबाई == 0 & amp; $ ('# telephone_f')। Val ()। लंबाई == 0) {

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
