问题描述

我正在尝试自动提交表单，但在编写的chrome扩展名中有延迟，但似乎没有提交。以下是我的表单和javascript：

I am trying to submit the form automatically with a delay in a chrome extension I am writing and it does not seem to be submitting. Below is my form and javascript:

function submitForm() { // submits form
    document.getElementById("ismForm").submit();
}

if (document.getElementById("ismForm")) {
    setTimeout("submitForm()", 5000); // set timout
}


<form method="post" id="ismForm" name="ismForm" action="http://www.test.com" class="">
<label for="searchBox">Search </label>
<input type="text" id="searchBox" name="q" value=""> <input type="hidden" id="sayTminLength" value="3"><input type="hidden" id="coDomain" value="US"><input class="button" type="submit" id="search.x" name="search.x" value="Search" autocomplete="off">
</form>

推荐答案

不知道上下文，但是可能该页面尚未完全加载-您可以尝试

Don't know the context, but it might be that the page has not been loaded yet completely - you might try putting

if (document.getElementById("ismForm")) {
    setTimeout("submitForm()", 5000); // set timout
}

。另外，请尝试在setTimeout之前和SubmitForm（）的开头放置一个简单的警报，以确保首先触发了超时。

in body onLoad() event. As another thing, try putting as simple alert before setTimeout and at the start of submitForm() to confirm the timeout is getting fired in the first place.
