jQuery推送img元素

jQuery pushing an img element

本文关键字：元素 img 推送 jQuery      更新时间：2023-09-26

我想获取所有表行数据，将它们推送到一个数组中，然后再将它们取回。但目前我只能获得前三列的值，但无法获得图像的src。

我尝试了data.push($(this).val(), $('img').attr('src'));，但没有成功。

                      data = [];
                      $("#car-control-sum tbody>tr").remove();
                        $("#car-control-table tbody select, #car-control-table tbody input, #car-control-table tbody img").each(function(){
                            data.push($(this).val());
                        });
                        <table data-role="table" id="car-control-table" class="ui-responsive ui-shadow">
                        <thead>
                        <tr>
                            <th style="width:158px;border-bottom: 1px solid #d6d6d6;">Kontrollpunkt</th>
                            <th style="width:110px;border-bottom: 1px solid #d6d6d6;">OK</th>

如何将图像src推送到数据数组中

考虑使用.prp（）而不是.attr（）

var src = $('#image-id').prop('src');
data.push(src);

尝试用this.value代替$(this).val()

   $("#car-control-table tbody select, #car-control-table tbody input, #car-control-table tbody img")
   .each(function() {
     data.push(this[this.nodeName === "input" ? "value" : "src"])
   });


var data = [];
                      //$("#car-control-sum tbody>tr").remove();
                      $("#car-control-table tbody select, #car-control-table tbody input, #car-control-table tbody img").each(function() {
                        data.push(this.value || this.src);
                      });
console.log(data)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table data-role="table" id="car-control-table" class="ui-responsive ui-shadow">
  <thead>
    <tr>
      <th style="width:158px;border-bottom: 1px solid #d6d6d6;">Kontrollpunkt</th>
      <th style="width:110px;border-bottom: 1px solid #d6d6d6;">OK</th>
      <th style="width:158px;border-bottom: 1px solid #d6d6d6;">Kommentar</th>
      <th style="width:110px;border-bottom: 1px solid #d6d6d6;">Ta bilde</th>
      <th style="width:110px;border-bottom: 1px solid #d6d6d6;">Det.</th>
    </tr>
  </thead>
  <tbody>
    <tr class="car-row">
      <td>
        <select class="select-lys">
          <option value="Stotdempere">Stotdempere, fjaerer</option>
        </select>
      </td>
      <td>
        <select id="checkup_ok" data-role="slider" style="height:100px;">
