Question

JavaScript函数以双引号返回div。喜欢 -

function Callback()
{
    return "<div>  <a href='javascript:void(0); >  ENGLISH </a> </div>";
}

我想检查document.getElementById（＆＃39; language＆＃39;）。value == ENGLISH然后将颜色应用于ENGLISH字。那么如何将JavaScript变量与concatenate匹配。
在此先感谢。

Answer 1

试试这个：

<div id='testElem'><a href='javascript:void(0)'>ENGLISH</a></div>
<script>
  function Callback()
  {
    return "<div id='testElem'><a href='javascript:void(0)'>ENGLISH</a></div>";
  }
  function check()
  {
    if(document.getElementById('language').value == "ENGLISH")
    {
      console.log(document.getElementById("testElem").childNodes[0].style.color = 'red');
    }
  }
  check();
</script>

Answer 2

         function Callback()
        {
            return "<div id='language'><a href='javascript:void(0);'> ENGLISH </a></div>";
        }
    var jslanguage=document.getElementById("language").textContent;
    jslanguage=jslanguage.trim() ;// will get the text ENGLISH.
if(jslanguage== "ENGLISH"){
  document.getElementById("language").style.color = "green";
}

Answer 3

不确定这是否是您想要的：

<div id="language" value="ENGLISH">
</div>

var cookieValue = document.getElementById("language").getAttribute('value');
if(cookieValue == "ENGLISH"){
  document.getElementById("language").style.color = "green";
}

如何在条件和concatenate中匹配值
