如何選擇具有多個下拉選項的給定行中特定下拉列表的值？

Question

我有兩個下拉選項名稱和值的許多形式，我想選擇名稱的選項是一個數組中的變量，像這樣。

for (i = 0;i<noOfElements;i++) 
      { 
       var resultHtml = theModule.getHtml("rowformtemplate", {}); 
      //load html of form with fields **name** and **value** as dropdown 
       $(section).append(resultHtml); 
      //append html to a div 
       var optValue = namearray[i]; 
      //from list of optons this value should be selected 
       var form = $(section).find(".row-template"); 
      //find all forms in the section 
       var row= form[form.length-1]; 
      //select latest form 
      //How to select name field "name" of current row and set it to be optvalue which is a variaable something like this. but it selects name field of all form and sets it to optValue 
       $("select[name^='name'] option[value=" + optValue + "]").attr("selected","selected"); 
      }

在您最終的jquery選擇器中，您正在瀏覽完整的html文檔而不是最新的表單。

請嘗試以下

$(row).find("select[name='name'] option[value='" + optValue + "']").attr("selected","selected"); 

，或者使用最新的jQuery

$(row).find("select[name='name'] option[value='" + optValue + "']").prop("selected",true);
