试图比较2字符串if语句[关闭]

问题描述：

I am trying to compare 2 strings, but there are not comparing as I would like. I am getting a value from a div and converting it to a string, when I find the typeof it is telling me is a string but still it is passing by the if statement.

When I write.document they both look the same. Thanks

<div id="countries"><?php $geoplugin->locate(); echo"{$geoplugin->countryName}"?> </div> 

<script>
                 var country = document.getElementById("countries");
                 var count = country.innerHTML;
                 var newc = String(count);


                 if ( newc === "Ireland" ){
                    document.write("this is ireland");
                    alert("You are from Ireland");

                 }else{
                    document.write("You Live in " + newc);
                                    //alert(typeof newc);                  
                    //alert(newc);

                 }

                 </script>

我正在尝试比较2个字符串，但没有按照我的意愿进行比较。我从div获取一个值并将其转换为字符串，当我发现它的类型告诉我是一个字符串但仍然通过if语句。 p>

当我写.document时，它们看起来都一样。谢谢 p>

 ＆lt; div id =“countries”＆gt;＆lt;  ？php $ geoplugin-＆gt; locate（）; 回声 “{$ geoplugin-＆GT;国家名称}” ＆GT？;  ＆LT; / DIV＆GT;  
 
＆lt; script＆gt; 
 var country = document.getElementById（“countries”）; 
 var count = country.innerHTML; 
 var newc = String（count）; 
 
 
 if（newc =  ==“爱尔兰”）{
 document.write（“这是爱尔兰”）; 
提醒（“你来自爱尔兰”）; 
 
}其他{
 document.write（“你住在”）  + newc）; 
 // alert（typeof newc）;  
 //警告（newc）; 
 
} 
 
＆lt; / script＆gt; 
  code>  pre> 
  div>

答

From your HTML it looks like you've got a trailing space after the <?php ...> instruction. So whatever is there, it won't exactly equal "Ireland". Try using trim to remove any whitespace from the ends of your string.

var newc = String(count).trim();
