Question

값으로 이름을 찾는 방법은 무엇입니까? 나는 이름이 "Obsah balení :"이며 값을 3,18m² 또는 직접 3,18으로 돌려 주어야합니다.

코드 :

<table id="product-detail-info" class="pr-list-parametes"> 
    <tbody> 
     <tr> 
     <td class="pr-detail-parameter-name"> 
      Frézováná hrana: 
     </td> 
     <td class="pr-detail-parameter-value"> 
      ne 
     </td> 
     </tr> 
     <tr> 
     <td class="pr-detail-parameter-name"> 
      Obsah balení: 
     </td> 
     <td class="pr-detail-parameter-value">3,18 m²</td> 
     </tr> 
     <tr> 
     <td class="pr-detail-parameter-name"> 
      Počet desek v balení: 
     </td> 
     <td class="pr-detail-parameter-value">7 ks</td> 
     </tr> 
     <tr> 
     <td class="pr-detail-parameter-name"> 
      Počet m² na paletě: 
     </td> 
     <td class="pr-detail-parameter-value">127,2 m²</td>

    .next() 
 
    // get the text contents 
 
    .text() 
 
)

이 당신을 위해 작동합니다

var getText = $('#product-detail-info tr td').filter(function(){ 
    return $.trim($(this).text()) == "Obsah balení:"; 
}).siblings('td').text(); 

alert(getText);
