Question

我尝试用jquery mobile从数据库填充带有单选按钮的表。当我直接在HTML中创建表时，该表是可以的，但是通过jscript创建相同的表，结果完全不同。在这个例子中，每个表只有一行，但我的目的是从数据库创建表行。

Answer 1

您可以通过复制和粘贴一些在线工具（例如Plunker或Fiddle）轻松查明HTML中是否存在某些问题：

如果从数据库数据中编写HTML，首先要注意的是保留HTML元素的唯一标识符。剩下的只是耐心和毅力。恕我直言，实现这种无聊任务的最简单方法是将字符串组成HTML，您可以随时在在线工具中查看（＆＃34; Tidy＆＃34;）。

最后，您可以在一次拍摄中插入和增强整个HTML。对于新插入的内容，容器上的JQM .enhanceWithin()就足够了，这里不需要所有append内容。

＆＃13;

$(document).on("pageshow", "#page1", function() {
  var html = "";
  $("#categories").html(html); // clean-up

  // start the tables loop 
  var sectionId = "service-1"; // compose unique id's
  html += '<table data-role="table" data-mode="columntoggle" class="ui-responsive table-stroke" id="' + sectionId + '" data-column-btn-text="Columns...">';
  html += '<thead><tr><th data-priority="1">Name</th><th data-priority="2">Vote</th></tr></thead>';
  html += '<tbody>';

  // start the rows loop
  html += '<tr>';
  var retServiceName = 'James Smith by jquery';
  html += '<td>' + retServiceName + '</td>';
  html += '<td>';
  html += '<fieldset data-role="controlgroup" data-type="horizontal" data-mini="false">';
  var rowId = "radio-choice-b1"; // compose unique id's

  // start the choices loop, compose unique id's
  var choiceVal = "0";
  var choiceId = rowId + "-" + choiceVal;
  var choiceLabel = "Yes";
  html += '<input type="radio" name="' + rowId + '" id="' + choiceId + '" value="' + choiceVal + '"><label for="' + choiceId + '">' + choiceLabel + '</label>';

  var choiceVal = "1";
  var choiceLabel = "No";
  var choiceId = rowId + "-" + choiceVal;
  html += '<input type="radio" name="' + rowId + '" id="' + choiceId + '" value="' + choiceVal + '"><label for="' + choiceId + '">' + choiceLabel + '</label>';

  var choiceVal = "2";
  var choiceLabel = "Null";
  var choiceId = rowId + "-" + choiceVal;
  html += '<input type="radio" name="' + rowId + '" id="' + choiceId + '" value="' + choiceVal + '"><label for="' + choiceId + '">' + choiceLabel + '</label>';

  html += '</fieldset>';
  html += '</td>';
  html += '</tr>';

  html += '</tbody>';
  html += '</table>';
  console.log(html); // check the whole html

  $("#categories").html(html);
  $("#categories").enhanceWithin();

});
