jQuery大写单词定位器 [英] jQuery Uppercase word locator

问题描述

我需要找到在<p> </p>之间用大写字母书写的超过4个字符的单词，并为其添加样式(例如斜体).

I need to locate words for more than 4 characters that are written between <p> </p> in uppercase and add them a style (ex. italic).

我了解函数isUpperCase()，但是不知道如何应用它来检查字符串是否超过4个字符.

I know about the function isUpperCase() but don't know how to apply it to check if the string is more than 4 characters.

function isUpperCase( string ) {
    (?)
}

谢谢.

推荐答案

var ps = [].slice.call(document.getElementsByTagName("p"))

ps.forEach(function (p) {
  p.textContent.split(" ").forEach(function (word) {
    if (word.length > 4 && word.toUpperCase() === word) {
      // 4character UPPERCASE word
    }
  })
})
