我的表单在Firefox和IE中运行良好。在调用onsubmit时,它调用js函数并验证代码,如果验证良好,则提交表单。
但是,在Chrome中,它不会进行验证,而只是直接提交表单。
我不确定为什么会这样,搜索很多但是徒劳无功。
任何帮助都会很有助于解决这个问题。
表格代码:
<form name="myform" action="queryfeedback.php" method="post" onSubmit="return validateForm(myform);">
<label for="labelField_Name" id="idLabel_Name"></label>
<input type="text" name="nameField_Name" id="idField_Name" placeholder="Enter your name here"/>
<br />
<label for="labelField_EMail" id="idLabel_EMail"></label>
<input name="nameField_EMail" type="text" id="idField_EMail" placeholder="Enter your E-Mail address here" />
<br />
<label for="labelField_Message" id="idLabel_Message"></label>
<textarea name="nameField_Message" id="idField_Message" placeholder="Enter your message for us here"></textarea>
<br />
<input type="Submit" name="nameSubmit" id="idButton_Submit" value="Submit" alt="Submit Button"/>
</form>
验证码:
function validateForm(form)
{
alert(form.nameField_Name.value);
//alert(formValueEMail.value);
//alert(formValueMessage.value);
if(form.nameField_Name.value=='')
{
alert("Name field is required. Please fill it in.");
form.nameField_Name.focus();
form.nameField_Name.select();
return false;
}
if(form.nameField_Name.value=='Enter your name here')
{
alert("Name field is required. Please fill it in.");
form.nameField_Name.focus();
form.nameField_Name.select();
return false;
}
if(form.nameField_EMail.value=='')
{
alert("E-Mail Address field is required. Please fill it in.");
form.nameField_EMail.focus();
form.nameField_EMail.select();
return false;
}
if(form.nameField_EMail.value=='Enter your E-Mail address here')
{
alert("E-Mail Address field is required. Please fill it in.");
form.nameField_EMail.focus();
form.nameField_EMail.select();
return false;
}
//Checking for correct format of EMail address.
var x=document.forms["myform"]["nameField_EMail"].value;
var atpos=x.indexOf("@");
var dotpos=x.lastIndexOf(".");
if (atpos<1 || dotpos<atpos+2 || dotpos+2>=x.length)
{
alert("Not a valid e-mail address");
return false;
}
if(form.nameField_Message.value=='')
{
alert("Message field is required. Please fill it in.");
form.nameField_Message.focus();
form.nameField_Message.select();
return false;
}
if(form.nameField_Message.value=='Enter your message for us here')
{
alert("Message field is required. Please fill it in.");
form.nameField_Message.focus();
form.nameField_Message.select();
return false;
}
return true;

尝试传入event参数并运行event.preventDefault()
,以便在验证之前停止提交表单。

关闭函数'validateForm'。因此可能会抛出错误。onsubmit="return validateForm(this);"
请注意,属性名称为onsubmit
,没有驼峰大小写且参数为this
validateForm
应该是一个全局函数。
