Question

想要搜索文本并获得匹配项：

WARN

我正在搜索RegExp()字并使用{{1}}方法进行模式，但它不起作用。

Answer 1

两个问题：

将var pattern = new RegExp("/" + text + "/g");更改为var pattern = new RegExp(text, "g"); RegExp，希望将这些标志用作第二个参数
选择器不正确。 $('Test').text().。没有使用$('#Test').text().

＆＃13;

function searchText(text) {
  var pattern = new RegExp(text, "g");
  var totalMatchCount = ($('#Test').text().match(pattern) || []).length;

  console.log(totalMatchCount);
  document.getElementById('result').innerHTML = JSON.stringify($('#Test').text().match(pattern), 0, 4);
}
