这里是我的代码片段:使用CasperJS/Javascript提交表单?
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()
})
此代码应该与sendKeys
填写之后提交的网站上(Reddit.com)存在的形式。它完成填写文本框(我可以通过截图通过casper.capture
)看到,但不提交文本。我原本以为这是因为一个错误的CSS选择器,但我不再确定。这似乎也是卡斯帕因为action='#'
属性而没有发送表单,所以在提交表单之前将其删除。我对下一步尝试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">
<span class="help-toggle toggle" style="">
<a class="option active " href="#" tabindex="100" onclick="return toggle(this, helpon, helpoff)">formatting help</a>

请正确格式化您的标记。另外,我没有看到您的脚本以及您如何验证没有任何事情发生。你正在截图吗?还是你正在看这些请求? –
@Artjom B.通过casper.capture使用屏幕截图。如果帖子确实通过,我也可以看到脚本的结果(在Reddit.com上)。现在修复标记。 –
请注册到'resource.error','page.error','remote.message'和'casper.page.onResourceTimeout'事件([Example](https://gist.github.com/artjomb/4cf43d16ce50d8674fdf) )。也许有错误。 –
