這裏是我的代碼片段:使用CasperJS/Javascript提交表單?
this.sendKeys('.usertext.cloneable > div > div.md > textarea', "Message");
//...
this.evaluate(function(){
var entry = document.getElementsByClassName("usertext cloneable")[0].id;
document.getElementById(entry).removeAttribute("action")
document.querySelector('#'+entry).submit()
})
此代碼應該與sendKeys
填寫之後提交的網站上(Reddit.com)存在的形式。它完成填寫文本框(我可以通過截圖通過casper.capture
)看到,但不提交文本。我原本以爲這是因爲一個錯誤的CSS選擇器,但我不再確定。這似乎也是卡斯帕因爲action='#'
屬性而沒有發送表單,所以在提交表單之前將其刪除。我對下一步嘗試的方式感到不知所措。
而且形式:
<form action="#" class="usertext cloneable" onsubmit="return post_form(this, 'comment')" id="form-t3_3gp8yji5i">
<input type="hidden" name="thing_id" value="t3_3gp8yj">
<div class="usertext-edit md-container" style="">
<div class="md">
<textarea rows="1" cols="1" name="text" class=""></textarea>
</div>
<div class="bottom-area">

<a class="option active " href="#" tabindex="100" onclick="return toggle(this, helpon, helpoff)">formatting help</a>

請正確格式化您的標記。另外,我沒有看到您的腳本以及您如何驗證沒有任何事情發生。你正在截圖嗎?還是你正在看這些請求? –
@Artjom B.通過casper.capture使用屏幕截圖。如果帖子確實通過,我也可以看到腳本的結果(在Reddit.com上)。現在修復標記。 –
請註冊到'resource.error','page.error','remote.message'和'casper.page.onResourceTimeout'事件([Example](https://gist.github.com/artjomb/4cf43d16ce50d8674fdf) )。也許有錯誤。 –
