无法将Js变量绑定到表列标题标记中

Question

var q = "SELECT Name, Address FROM Login where Login = 'app'"; 
var tablerow = "<tr> <td title="+q+"></td> </tr>" 

当我将光标移到表格列上时。它显示：

SELECT Name，Address FROM Login Login =

未显示完整字符串

Answer 1

对我来说这很好用：

所以我只是使用这些行：

＆＃13;

＆＃13;

window.onload = function() {
    hoverinfo.title = "SELECT Name, Address FROM Login where Login = 'app'";
}

＆＃13;

<table>
  <tr> 
    <td id="hoverinfo">hover</td>
  </tr> 
</table>

＆＃13;

＆＃13;

＆＃13;

  

使用动态代码（fiddle）：

＆＃13;

＆＃13;

var q = "SELECT Name, Address FROM Login where Login = 'app'";
var tablerow = "<tr> <td title=\""+q+"\"> title </td> </tr>"

window.onload = function() {
  table.innerHTML += tablerow
}

＆＃13;

<table id="table">


</table>

＆＃13;
