任何能够帮助我的人?
document.MyForm.Name.value.toLowerCase()。equals(''viagra'')
你有什么理由不能只需执行以下操作:
document.forms [" MyForm"]。elements [" Name"]。toLowerCase()==" viagra"
因为没有String方法等于。
web.dev写道:< blockquote class =post_quotes> document.MyForm.Name.value.toLowerCase()。equals(''v iagra'')
你有什么理由不能只需执行以下操作:
document.forms [" MyForm"]。elements [" Name"]。toLowerCase()==" viagra"
因为那里是没有String方法等于。
没用。 :-(

Torbj?姓Pettersen写道:web.dev写道:document.MyForm.Name.value.toLowerCase()。equals (''v iagra'')
是否有理由不能简单地执行以下操作:
document.forms [" MyForm" ;]。元素[" Name"]。toLowerCase()==" viagra"
因为没有String方法" equals"。
>不工作。: - (
JavaScript String对象中没有方法equals。使用简单的
比较而是建议:
//错误:
if(document.MyForm.Name.value.toLowerCase()。equals(''viagra'') )
//右:
if(document.MyForm.Name.value.toLowerCase()==''viagra'')
A form input where value = viagra is to be rejected using a javascript,
but it doesn''t work at all.
Line 30 and on is where the last attempt to get the code to work is.

Is there a reason why you can''t simply do the following:
document.forms["MyForm"].elements["Name"].toLowerCase() == "viagra"
Because there is no String method "equals".

There is not method "equals" in JavaScript String object. Use simple
comparison instead as suggested:
// WRONG:
if (document.MyForm.Name.value.toLowerCase().equals('' viagra''))
// RIGHT:
if (document.MyForm.Name.value.toLowerCase() == ''viagra'')
