遺莣 回答

onShow在request返回前執(zhí)行，所以你在onShow里面打印question的時候，肯定是沒有值的。

那么為什么同樣是在onShow里面打印data，data里面的question卻有值呢？是因?yàn)閏hrome打印出來的對象并不是簡單的打印它當(dāng)時的值，而是打印的是該對象的引用，所以之后你對該對象的所有改變，也會反映到之前的打印結(jié)果中去。

一個簡單的辦法驗(yàn)證這一點(diǎn)，你在request里面打一個斷點(diǎn)，當(dāng)執(zhí)行到這個斷點(diǎn)的時候，你看看onShow里面打印的data是不是有值。然后放開斷點(diǎn)，再看是不是有值。然后你就明白了。

自己已解決

            let html = this.getHtmlContent();
            let html_ = new Blob([html],{ "type" : "text/html;charset=utf-8" })
            let formdata = new FormData();
            formdata.append('file', html_, `sdf.html`);
            axios({
                method: 'post',
                url: url,
                data:formdata,

放開她 回答

開始我也感覺是能修改成功的，但是試了一下你的代碼后，也發(fā)現(xiàn)了你說的問題。然后看了 getpwnam()的源碼后，我想可以這樣解釋。
首先說一下你的第一次的代碼為什么不能成功：
char *pw_geco = "code1/code2/code3//textField/usergecosparsed";
你這樣定義的是使 pw_gecon 這個指針變量指向了 "code1/code2/code3//textField/usergecosparsed" 這個字符串常量，所以接下來你的代碼想要改變這個常量的值，所以系統(tǒng)不會讓你修改。所以如果你把代碼改成這樣：
char *pw_geco=NULL;
char pw_geco=(char)malloc(200); //為這個 pw_geco指針變量申請內(nèi)存,存放字符串.
sprintf(pw_geco,"%s","code1/code2/code3//textField/usergecosparsed");
這樣你再去改變通過 pw_geco 這個指針變量改變的就不是常量字符串。而是 pw_geco 指向的一個可變的字符串。

自己弄錯了順序：
$("#condition-range").html(conditionRangeHtml);
$("#condition-field").html(conditionFieldHtml);
$.parser.parse($('#condition-range').parent());
$.parser.parse($('#statistics-date').parent());
先加到頁面上，再用$.parser.parse加載easyui樣式即可。

但是，二級域名是可以的，比如 www.baidu.com 理論上可以獲取 zhidao.baidu.com的cookie

你可以自行檢查修改返回值, 如影響行數(shù)為0可以自己拋出異常, 否則數(shù)據(jù)庫來講,執(zhí)行update修改多少行對是語義上正確的.

帥到炸 回答

html讀取是自上而下的，建議先加載css層疊樣式文件再加載js文件，這樣即使網(wǎng)慢的時候也會先顯示出大體輪廓，如果先加載js則會影響頁面樣式。

未命名 回答

作用域的理解是沒問題的，除此之外你還應(yīng)該理解this。你的return this.name你要搞清楚this指向了誰。

var ele = obj.getName();

此時的ele是一個函數(shù)，等價于function () {return this.name}

而你直接執(zhí)行ele()的時候，這個this指向的是global，在瀏覽器中就是window。

換個執(zhí)行方式：

ele.call(obj); // "小王"
