javascript - PHP - echo 语句中缺少 onClick 输出的输出

Question

echo"<div class='btn-likes'><input type='button' title='".ucwords($str_like)."' class='".$str_like."' onClick='addLikes(".$tutorial['id'].",".$str_like.")' /></div>";

上述代码的输出为:

<input title="Like" class="like" onclick="addLikes(51,like)" type="button">

输出我想要的是:

<input title="Like" class="like" onclick="addLikes(51,'like')" type="button">

onclick="addLikes(51,'like')"中缺少撇号

我已经尝试过:

echo"<div class='btn-likes'><input type='button' title='".ucwords($str_like)."' class='".$str_like."' 
          onClick='addLikes(".$tutorial['id'].",'".$str_like."')' /></div>";

输出非常直观:

<input title="Like" class="like" onclick="addLikes(51," like')'="" type="button">

有人可以帮助我吗？

您需要转义引号:

echo '<div class="btn-likes"><input type="button" 
    title="'.ucwords($str_like).'" class="'.$str_like.'" 
    onClick="addLikes('.$tutorial['id'].',\''.$str_like.'\')" /></div>';
