cc_christian 非常感謝您為我解答這個(gè)問題,但是這好像只限於使用數(shù)字,有幾個(gè)<textarea>他就往上加上去
其實(shí)我想達(dá)成的效果是連英文或國(guó)字也可以實(shí)現(xiàn),例如我的下拉式選單內(nèi)容有a-e和36計(jì)1-5計(jì)
當(dāng)我點(diǎn)選a-e他能填入下面五個(gè)<textarea>依序1.a 2.b 3.c 4.d 5.e
當(dāng)我再點(diǎn)選36計(jì)1-5計(jì)他能接著填入1.瞞天過(guò)海 2.圍魏救趙 3.借刀殺人 4.以逸待勞 5.趁火打劫而不刪掉之前的a-e
不知道這樣有沒有可能實(shí)現(xiàn)呢?

有償幫忙寫一段js 正則

熊出沒回答

就是把一段文本中除了a或者img以外的所有標(biāo)簽都干掉，然后干掉a以及img中的css？
如果我沒有理解錯(cuò)的話，大致是這樣的：

(() => {
  let str = `
  <p style="color: blued">text</p>
  <img src="XXX" style="color: red" />
  <a href="XXX" style="color: red" >Link</a>
  <p>text</p>
  `

  // 邏輯分兩塊：
  // 1. 將非`img`、`a`標(biāo)簽的tag替換為轉(zhuǎn)義符
  // 2. 將`img`、`a`標(biāo)簽中的`style`干掉

  let text = str.replace(/<(\/?)([\w]+)(.*?)(\/?)>/g, (_, selfClosing, tag, content, closing) => {
    if (['img', 'a'].includes(tag.toLowerCase())) {
      return `<${selfClosing}${tag}${content.replace(/style=".*?"/g, '')}${closing}>`
    } else {
      return `&lt;${selfClosing}${tag}${content}${closing}&gt;`
    }
  })

  console.log(text)
})()

如果對(duì)的話，也別什么有償了，覺得對(duì)你有幫助的話，點(diǎn)個(gè)follow也是極好的：https://github.com/Jiasm

Spring 怎么弄代碼混淆和過(guò)時(shí)？

蝶戀花回答

簡(jiǎn)單好用 Proguard 的maven插件，簡(jiǎn)單意味著代碼還是很容易被反解的，只是麻煩而已。

這里有個(gè)不錯(cuò)的例子：

vue多頁(yè)面如何重定向？

傲嬌范回答

今天剛好遇到了這個(gè)問題。
沒找到什么好的辦法，暫時(shí)直接用原生js解決了

router.beforeEach((to, from, next) => {
  if (to.meta.requireAuth) {
    if (localStorage.getItem('token')) {
      next()
    } else {
      window.location.href = 'index.html#/login'
    }
  } else {
    next()
  }
})

maven中并沒有配置私服,但是下載的時(shí)候仍會(huì)請(qǐng)求私服

這個(gè)應(yīng)該是你 IDE 的 Maven 倉(cāng)庫(kù)配置吧。

你看一下這個(gè)配置：

golang json 返回不需要輸出的 struct 字段

九年囚回答

Struct values encode as JSON objects. Each exported struct field becomes a member of the object unless

the field's tag is "-", or
the field is empty and its tag specifies the "omitempty" option.

The empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. The object's default key string is the struct field name but can be specified in the struct field's tag value. The "json" key in the struct field's tag value is the key name, followed by an optional comma and options. Examples:

// Field is ignored by this package.
Field int json:"-"

// Field appears in JSON as key "myName".
Field int json:"myName"

// Field appears in JSON as key "myName" and
// the field is omitted from the object if its value is empty,
// as defined above.
Field int json:"myName,omitempty"

// Field appears in JSON as key "Field" (the default), but
// the field is skipped if empty.
// Note the leading comma.
Field int json:",omitempty"
The "string" option signals that a field is stored as JSON inside a JSON-encoded string. It applies only to fields of string, floating point, integer, or boolean types. This extra level of encoding is sometimes used when communicating with JavaScript programs:

Int64String int64 json:",string"
The key name will be used if it's a non-empty string consisting of only Unicode letters, digits, dollar signs, percent signs, hyphens, underscores and slashes.
