问题描述
< form id =formonsubmit =return false;>
< input style = position:absolute; top:80%; left:5%; width:40%; type =textid =userInput>
< input style = position:absolute; top:50%; left:5%; width:40%; type =submitonclick =name()>
< / form>
,这是javascript部分:
function name()
{
var input = document.getElementById(userInput);
alert(输入);
}
解决方案
name
是JavaScript中的保留字。将函数名改为别的。
请参阅 http://www.quackit.com/javascript/javascript_reserved_words.cfm
< form id = formonsubmit =return false;>
< input style =position:absolute; top:80%; left:5%; width:40%; type =textid =userInput/>
< input style =position:absolute; top:50%; left:5%; width:40%; type =submitonclick =othername(); />
< / form>
函数othername(){
var input = document.getElementById(userInput)。value;
alert(输入);
}
i am making a game and at the start it asks for your name. I want this name to be saved as varible. i have this html code:
<form id="form" onsubmit="return false;">
<input style=position:absolute;top:80%;left:5%;width:40%; type="text" id="userInput">
<input style=position:absolute;top:50%;left:5%;width:40%; type="submit" onclick="name()">
</form>
and this is javascript part:
function name()
{
var input = document.getElementById("userInput");
alert(input);
}
解决方案
It doesn't work because name
is a reserved word in JavaScript. Change the function name to something else.
See http://www.quackit.com/javascript/javascript_reserved_words.cfm
<form id="form" onsubmit="return false;">
<input style="position:absolute; top:80%; left:5%; width:40%;" type="text" id="userInput" />
<input style="position:absolute; top:50%; left:5%; width:40%;" type="submit" onclick="othername();" />
</form>
function othername() {
var input = document.getElementById("userInput").value;
alert(input);
}
