我在html中有一个问题。我已经编写了我的代码,但现在我想在有人点击提交按钮后打开一个新窗口,在这个新窗口中,他或她输入的文本将被显示。
<html>
<body>
<font face="Arial,Helvetica">Hello!
</body>
<p><label for="vname">Tell me something:
<input type="text" id="vname" name="vname">
</font>
<body>
</p>
</label>
<input type="submit" value="Submit" onclick="myAlert()">
</html>

此代码将让您打开一个新窗口并使用表单值填充
function myAlert() {
var NewWindow= window.open();
var nameValue = document.getElementById("vname").value;
NewWindow.document.write("<p>Some text followed by form value </p>"+ nameValue );
}

您缺少一些东西。您需要包含表单并阻止表单发送。这是一个让你走向正确方向的例子!
items = new List<TextCell>();
items.Add(new TextCell { Text = "Cake", TextColor = Color.Green, Detail = "12 hours left!", DetailColor = Color.Black});
items.Add(new TextCell { Text = "Pie", TextColor = Color.Green, Detail = "14 hours left!", DetailColor = Color.Black });
var buy = new ContentPage
{
Title = "Buy",
Content = new StackLayout
{
VerticalOptions = LayoutOptions.Center,
Children = {
new ListView
{
ItemsSource = items,
ItemTemplate = new DataTemplate(typeof(TextCell))
}
}
}
};
(function(){
var f, s, w;
f = document.forms.submit;
f.addEventListener("submit", function(e){
e.preventDefault();
s = "Name: ";
s += f.name.value;
s += "<br/>";
s += "Last Name: ";
s += f.last.value;
w = window.open();
w.document.write(s);
});
}());

首先,您应该使用<form>
。否则,<input type="submit">
并没有真正做任何事情。完成后,请使用window.open()
。
<form onsubmit="return false;">
<label for="vname">Tell me something:
<input type="text" id="vname" name="vname">
<input type="submit" value="Submit" onclick="myAlert()">
</form>
JavaScript:
function myAlert() {
var results = window.open();
var vname = document.getElementById("vname").value;
results.document.write(vname);
}
基本上,JS获取输入的值,打开一个新页面,然后使用document.write
显示结果。
<form onsubmit="myAlert(); return false">
<label for="vname">Tell me something:
<input type="text" id="vname" name="vname">
<input type="submit" value="Submit">
</form>
JavaScript:
function myAlert() {
var vname = document.getElementById("vname").value;
document.write(vname);
}
