토론: js와 php에서 삼중 등호(===)와 이중 등호(==)의 차이점

<script></li>
<li>var priceOfApple = "3元"; // 苹果的价格</li>
<li>var priceOfBanana = "3.5元"; // 香蕉的价格</li>
<li>priceOfApple = parseInt( priceOfApple ); // 解析苹果的价格</li>
<li>var priceOfBanana2 = parseInt( priceOfBanana ); // 解析香蕉的价格</li>
<li>if( ( priceOfApple===3 ) && ( priceOfBanana2 === 3 ) // 检查解析是否成功</li>
<li>&& ( parseFloat( priceOfBanana ) ===3.5 ) ) </li>
<li>{</li>
<li>alert( "苹果的价格:"   priceOfApple // 输出水果的价格</li>
<li>  "n香蕉的价格的整数部分:"   priceOfBanana2</li>
<li>  "n香蕉的价格:"   parseFloat( priceOfBanana ) );</li>
<li>}</li>
