javascript - 想用javascript替换字符串中的Object标签

Question

我想用空格替换 javascript 中包含字符串的对象标记。

var tmpSearchPhrase ='<object data="data:text/html;
base64,PHNjcmlkb21haW4pOzwvc2NyaXB0Pg=="></object>';
tmpSearchPhrase.replace(/<object .*>.*<\/object>/,"");   

但它不是替换对象。

Answer 1

除非您将其转义，否则您不能在字符串中包含换行文字。

var tmpSearchPhrase ='<object data="data:text/html;
base64,PHNjcmlkb21haW4pOzwvc2NyaXB0Pg=="></object>';
// SyntaxError: Unexpected token ILLEGAL

var tmpSearchPhrase ='<object data="data:text/html;\
base64,PHNjcmlkb21haW4pOzwvc2NyaXB0Pg=="></object>';
// fine

tmpSearchPhrase.replace(/<object .*>.*<\/object>/,"");  // ""

您可能还忘记将结果分配给replace变量。

Answer 2

不要破坏字符串并重新分配 to 的返回replace值tmpSearchPhrase

tmpSearchPhrase ='<object data="data:text/html;base64,PHNjcmlkb21haW4pOzwvc2NyaXB0Pg=="></object>';
tmpSearchPhrase = tmpSearchPhrase.replace(/<object .*>.*<\/object>/,"");
