javascript - 如何使用 javascript string.replace

Question

我正在尝试替换:

The quick fox jumped over "tree"

与:

The quick fox jumped over "wall"

我已经尝试过这个:

var str = 'The quick fox jumped over "tree"';
          str.replace(/"tree"/g, '"wall"');

替换没有发生。 请帮忙

Answer 1

您只需在替换字符串后保存它即可。

var str = 'The quick fox jumped over "tree"'; 
str = str.replace('"tree"', '"wall"');
console.log(str);
