不是讓你導(dǎo)入組件,而是你用到了自定義組件<el-menu-collapse-transition>并沒(méi)有被注冊(cè),注冊(cè)方式:

<div id="example">
  <el-menu-collapse-transition></el-menu-collapse-transition>
</div>

<script>
import Vue from 'vue';
Vue.component('el-menu-collapse-transition', {
  template: '<div>A custom component!</div>'
})
</script>

使用 h+開(kāi)發(fā)app只需要你熟練前端開(kāi)發(fā),

文檔在這里,照著文檔抄就行了:

// 獲取所有audios
var audios = document.getElementsByTagName("audio");
// 暫停函數(shù)
function pauseAll() {
    var self = this;
    [].forEach.call(audios, function (i) {
        // 將audios中其他的audio全部暫停
        i !== self && i.pause();
    })
}
// 給play事件綁定暫停函數(shù)
[].forEach.call(audios, function (i) {
    i.addEventListener("play", pauseAll.bind(i));
})

用GET方法加載http://localhost/token.php頁(yè)面, 參數(shù)grant_type=client_credentials, -u后面的是用戶(hù)名和密碼.

@Feng_Yu 是對(duì)的, 加-d參數(shù)后,curl默認(rèn)按POST方法發(fā)送數(shù)據(jù)

String classPath = JsonUtils.class.getProtectionDomain().getCodeSource().getLocation().getPath();

JsonUtils.readJson(classPath + "test.json");

沒(méi)有問(wèn)題,vue本來(lái)就是一個(gè)漸進(jìn)式的框架,況且vue的作者尤雨溪多次說(shuō)道不要一提到vue就必須vue-cli,沒(méi)人逼迫你這樣做,完全可以在頁(yè)面引入當(dāng)做替換jquery的一個(gè)庫(kù)使用,作者本人也說(shuō)這在外國(guó)并不少見(jiàn)。而且新手是用這樣方式可以先適應(yīng)vue的語(yǔ)法糖,理解數(shù)據(jù)驅(qū)動(dòng)的思想,以后想上cli也減少點(diǎn)難度。

那就要看你在閱讀原文里放的是啥了,單看截圖的話,沒(méi)猜錯(cuò)應(yīng)該是在wx.error里寫(xiě)了個(gè)alert,還是建議用vConsole打log的方式來(lái)排錯(cuò)吧。

React不監(jiān)聽(tīng)數(shù)據(jù)對(duì)象,而是通過(guò)手動(dòng)調(diào)用setState()方法來(lái)觸發(fā)virtueDiff,以此對(duì)比前后來(lái)個(gè)狀態(tài)的不同,然后針對(duì)性的更改變化了的DOM結(jié)構(gòu)實(shí)現(xiàn)數(shù)據(jù)更新。這是我的理解,歡迎大神拍磚。

簡(jiǎn)單來(lái)說(shuō)是有特別的標(biāo)志位。Wiki上是這么說(shuō)的:

In IEEE 754 standard-conforming floating-point storage formats, NaNs are identified by specific, pre-defined bit patterns unique to NaNs. The sign bit does not matter. Binary format NaNs are represented with the exponential field filled with ones (like infinity values), and some non-zero number in the significand field (to make them distinct from infinity values). The original IEEE 754 standard from 1985 (IEEE 754-1985) only described binary floating-point formats, and did not specify how the signaling/quiet state was to be tagged. In practice, the most significant bit of the significand field determined whether a NaN is signaling or quiet. Two different implementations, with reversed meanings, resulted:
most processors (including those of the Intel and AMD's x86 family, the Motorola 68000 family, the AIM PowerPC family, the ARM family, the Sun SPARC family, and optionally new MIPS processors) set the signaling/quiet bit to non-zero if the NaN is quiet, and to zero if the NaN is signaling. Thus, on these processors, the bit represents an 'is_quiet' flag;
in NaNs generated by the PA-RISC and old MIPS processors, the signaling/quiet bit is zero if the NaN is quiet, and non-zero if the NaN is signaling. Thus, on these processors, the bit represents an 'is_signaling' flag.
The former choice has been preferred as it allows the implementation to quiet a signaling NaN by just setting the signaling/quiet bit to 1. The reverse is not possible with the latter choice because setting the signaling/quiet bit to 0 could yield an infinity.
The 2008 revision of the IEEE 754 standard (IEEE 754-2008) makes formal recommendations for the encoding of the signaling/quiet state.
For binary formats, the most significant bit of the significand field should be an 'is_quiet' flag. I.e. this bit is non-zero if the NaN is quiet, and zero if the NaN is signaling.
For decimal formats, whether binary or decimal encoded, a NaN is identified by having the top five bits of the combination field after the sign bit set to ones. The sixth bit of the field is the 'is_quiet' flag. The standard follows the interpretation as an 'is_signaling' flag. I.e. the signaling/quiet bit is zero if the NaN is quiet, and non-zero if the NaN is signaling. A signaling NaN is quieted by clearing this sixth bit.
For IEEE 754-2008 conformance, the meaning of the signaling/quiet bit in recent MIPS processors is now configurable via the NAN2008 field of the FCSR register. This support is optional in MIPS Release 3 and required in Release 5.[10]
The state/value of the remaining bits of the significand field are not defined by the standard. This value is called the 'payload' of the NaN. If an operation has a single NaN input and propagates it to the output, the result NaN's payload should be that of the input NaN (this is not always possible for binary formats when the signaling/quiet state is encoded by an 'is_signaling' flag, as explained above). If there are multiple NaN inputs, the result NaN's payload should be from one of the input NaNs; the standard does not specify which.

請(qǐng)教了好多人,感覺(jué)都沒(méi)有好的答案,只有一個(gè)答案感覺(jué)還可以,不過(guò)是無(wú)法解決這個(gè)問(wèn)題:

說(shuō)是微信的這個(gè)返回按鈕,開(kāi)始和瀏覽器沒(méi)關(guān)系,必須對(duì)頁(yè)面有操作才能是這個(gè)按鈕與瀏覽器產(chǎn)生關(guān)系,也就是說(shuō)一開(kāi)始這個(gè)返回按鈕就是返回聊天窗口的。
