我有一个似乎无法找到解决方案的问题。问题是这样的：我有一些jQuery，它将使按钮保持禁用状态，直到所有表单的字段都填满为止。当所有字段都填满时，将启用该按钮，但不会触发用于Google Recaptcha的javascript onSubmit事件。任何人都可以帮忙
代码如下：
//jquery to disable button until all fields are filled up
$().ready(function() {
// validate signup form on keyup and submit
$("#fbForm").validate({
rules: {
name: {
required: true
},
surname: {
required: true
},
terms: {
required: true
}
},
errorPlacement: function(error, element) {
return true;
},
submitHandler: function() {
}
});
$('#fbForm').change(function() {
if ($("#fbForm").valid()) {
$("#btnSubmit").removeAttr("disabled");
}
});
//recaptcha JS
function onSubmit(token) {
if (screen.width >= 768) {
document.getElementById("fbForm").submit();
}else if (screen.width <= 767){
document.getElementById("fbForm2").submit();
}
}<form id="fbForm"class="well form-horizontal" action="winesOfDistinction.php?send=true" method="post" data-toggle="validator">
<div class="form-group">
<label for="name "class="col-md-4 control-label">First Name</label>
<div class="col-md-4">
<div class="input-group">
<span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
<input type="text" placeholder="First Name" name="name" id="name" class="form-control" data-minlength="2" data-error="Minimum Lenght of First Name must be made up of at least 2 characters!" value="<?= $name ;?>" required>
</div>
</div>
<div class="help-block with-errors"></div>
</div>
<!-- Surname: Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="surname">Last Name</label>

在最后一行缺少}来关闭ready函数。先解决这个问题。

好的，缺少jquery验证程序和语法错误是导致此问题的原因。该代码段工作正常。您应使用可视代码作为编辑器，并请先解决语法错误，然后再在此处发布。
