变量不与'或'或\“回应

Question

第1行遇到一点问题，回应食品品牌的内容......

echo $hint='<a href="javascript:void(0)" onclick="javascript:document.contactForm.itemDetailTitle4.value=\"$brand\"; document.contactForm.itemDetailBrand4.value=4;">fill form</a>'.

$brand= $w->item(0)->childNodes->item(0)->nodeValue;

更新

      $hint='<a href="javascript:void(0)" onclick="javascript:document.contactForm.musicDetailTitle4.value="'.$artist.'"; document.contactForm.musicDetailArtist4.value=4;">fill form'.$artist."-".$title."-".$id."</a>";

Answer 1

它正在发生，因为变量不用单引号解析：

..."javascript:document.contactForm.itemDetailTitle4.value="'. $brand .'"; document...

使用连接，如上所述。

Answer 2

仅在引号之间解析变量

echo 'Text $var'; //apostrophe will not parse variable
echo "Text $var"; //citation marks will parse

在你的情况下，你应该这样做，这样你就不必与之抗争：

echo $hint='<a href="javascript:void(0)" onclick="javascript:document.contactForm.itemDetailTitle4.value="' . $brand . '"; document.contactForm.itemDetailBrand4.value=4;">fill form</a>'.

Answer 3

1. 首先 $brand= $w->item(0)->childNodes->item(0)->nodeValue;

2. 第二

   echo $hint='<a href="javascript:void(0)" onclick="javascript:document.contactForm.itemDetailTitle4.value="'.$brand.'"; document.contactForm.itemDetailBrand4.value=4;">fill form</a>'
