我正在为表单使用jQuery验证插件...请参阅下面的完整代码。虽然以下是检查所需的项目名称,但它不是检查长度,并允许提交。看错了什么?
<form method="post" id="new_space" data-remote="true" class="new_space" action="/spaces" accept-charset="UTF-8">
<label for="space_name">Name</label><br>
<input type="text" size="30" name="space[name]" id="space_name" class="text_field">
</form>
<script type="text/javascript">
$(document).ready(function () {
$("#new_space").validate({
errorLabelContainer: "#ui-dialog-errors",
wrapper: "p",
errorClass: "error",
invalidHandler: function() {
$("#ui-dialog-errors").hide().fadeIn();
},
rules: {
"space[name]":{required: true, minLength: 4}
},
messages: {
"space[name]":{ required: "Project Name required!", minLength: "Project Name's need 4+ characters" }
}
});
});
</script>
答案 0 :(得分:1)
将minLength
更改为minlength
(小写“l”)应该修复它。
对于您的第二个问题,假设form_submit
是您提交按钮的id
,这应该可以解决问题:
// Disable the submit button when first loaded
$("#form_submit").attr("disabled", "disabled");
$("input").change(function() {
// Check if the form validates
if($("#new_space").valid()) {
// Enable the button
$("#form_submit").removeAttr("disabled");
}
});
在JSFiddle上查看。
