Question

我正在尝试使用jQuery迭代输入字段表，获取每个值并连接到字符串。单击提交按钮，我想连接:input和:select的输入字段。我读到jquery输入选择器也选择了选择字段，但这似乎不是这里的情况。我尝试将多种类型传递到find()，但这也没有用。有什么提示吗？

这是 jQuery

 $("#SubmitButton").click(function(){
   var Teams = $(".NewTeam").length;   //working
   event.preventDefault(); 
   alert("clicked lets do ajax");
   for (var i=0; i < Teams; i++){
      $('.NewTeam').eq(i).find('input').each(function () {
        alert(this.value); // "this" is the current element in the loop
      });
   }
});

HTML标记

 <div class = "teams">
    <fieldset class="vfb-fieldset vfb-fieldset-1 str8-sports-roster-upload NewTeam"  style = "display: none">
     <table class = "PlayerInfoTable">
      <tr class = "PlayerRow">
       <td><strong style = "vertical-align:top">Player Info: </strong></td>
       <td><input class="teamInput" name = "player[]" type="text" placeholder="Player Full Name" required/></td>
       <td><input class="teamInput" name = "player[]" type="text" placeholder="Player Number" required/> </td>
       <td><select class="teamInput" name = "player[]" type="text" placeholder="Jersey Size" required/><option selected = "selected">Jersey Size</option><option>Youth Small</option><option>Youth Medium</option><option>Youth Large</option><option>Youth X-Large</option><option>Small</option><option>Medium</option><option>Large</option><option>Extra Large</option> </td>
       <td><select class="teamInput" name = "player[]" type="text" placeholder="Short Size"><option selected = "selected">Short Size</option><option>Youth Small</option><option>Youth Medium</option><option>Youth Large</option><option>Youth X-Large</option><option>Small</option><option>Medium</option><option>Large</option><option>Extra Large</option></select> </td>
       <td><select class="teamInput" name = "player[]" type="text" placeholder="Male/Female" required</select> <option>Male</option><option>Female</option> </td>
      </tr>
     </table>
    </fieldset>

Answer 1

正如您在此处使用event.preventDefault();一样，您应该将$("#SubmitButton").click(function(){更改为$("#SubmitButton").click(function(event){

当你使用eventHandler时，你应该添加一个参数。

在您的HTML中，您还应该进行更改，您已经使用了选择框，这需要标签，开始和结束，您还没有正确启动和结束标记，这是该行

<select class="teamInput" name = "player[]" type="text" placeholder="Male/Female" required</select> <option>Male</option><option>Female</option>

更改为

<select class="teamInput" name = "player[]" placeholder="Male/Female" required><option>Male</option><option>Female</option></select>

此外，您可以使用您的类选择器，其中.teamInput在每个元素中都是通用的。

很容易就可以加入jQuery，看看它是否正常工作。

$("#SubmitButton").click(function(event){
    event.preventDefault();
    $(".teamInput:input:visible").each(function() {
       alert($(this).val());
    });
});

Answer 2

替换

   $('.NewTeam').eq(i).find('input').each(function () {

只需

  $('.NewTeam').eq(i).find(':input').each(function () {

input仅选择输入标记，:input也会选择其他form-input elements。

Answer 3

首先，您需要将事件作为参数传递给您的点击功能，然后您需要修改.each的选择器以找到选择元素作为＆＃39;输入＆＃39;只会找到输入元素而不是选择元素：

$("#SubmitButton").click(function(event){
   var Teams = $(".NewTeam").length;   //working
   event.preventDefault(); 
   alert("clicked lets do ajax");
   for (var i=0; i < Teams; i++){
      $('.NewTeam').eq(i).find('input, select').each(function () {
          alert(this.value); // "this" is the current element in the loop
          console.info($(this).text() ); this will print in console in blue color the text of <option> as you have not assigned value attribute
      });
   }
});

jquery：输入选择器不选择：选择元素？
