【问题描述】：

我有带有 UTF-8 字符的 JSON 数据，我想搜索它类似于 SQL LIKE %value% 语句。

下面是代码 - 当你用英文写名字时它可以正常工作：

  jsonData ='[{"id":19,"cost":400,"name":"Ø§Ø³Ù„Ù…","height":198,"weight":35},{"id":21,"cost":250,"name":"ÙØ±ØØ§Ù†","height":216,"weight":54},{"id":38,"cost":450,"name":"Ø¹Ù„ÛŒ","height":147,"weight":22}]';
  array = JSON.parse(jsonData);
  var result = array.filter((x) => x.name.toLowerCase().indexOf("ا") >= 0);
  console.log(result);

这是与英文数据相同的代码，它工作正常

 jsonData ='[{"id":19,"cost":400,"name":"arian","height":198,"weight":35},{"id":21,"cost":250,"name":"Arkanss","height":216,"weight":54},{"id":38,"cost":450,"name":"Jumla","height":147,"weight":22}]';
  array = JSON.parse(jsonData);
  var result = array.filter((x) => x.name.toLowerCase().indexOf("r") >= 0);
  console.log(result);

最后通过简单地在页面中添加一个元标记来解决它

<meta http-equiv="Content-Type" content="text/html" charset="utf-8" />
