页面项共通校验validate

原生的校验插件不太好用，故项目中重写了validate.js文件！

下面为具体的用法步骤：

1. 需要实现的页面效果

2. 页面写法

<li><span><i class="redstar">*</i>重量</span>      <input type="text" name="loadLimit" class="input-txt w-s94" validate="required digits[8]"/> 吨</li>

3.  重量前面的必填标记css

.redstar{display: inline-block;vertical-align: top;color: #ff2400;}

4. 提交表单方法里面调用

// formid 表单id，前面不需要加"#"号var result = checkSingleForm(formid);if (!result) return;  //校验不通过返回

5. 引入validate.js

6. validate.js内容如下：

$('input,textarea,select').blur(function(){var $this = $(this);return validates.checkvalidate($this);});$('select').change(function(){var $this = $(this);return validates.checkselect($this);});//提交时验证单独form表单function checkSingleForm(id) {var istrue = true;$('#'+id+' input,#'+id+' textarea,#'+id+' select').each(function(i,val){var $this = $(val);istrue = validates.checkvalidate($this);if(!istrue) return false;});if(!istrue) {return false;}$('#'+id+' select').each(function(i,val){var $this = $(val);istrue = validates.checkselect($this);if(!istrue) return false;});return istrue;}//提交时验证所有表单function checksub() {var istrue = true;$('input,textarea,select').each(function(i,val){ var $this = $(val);istrue = validates.checkvalidate($this);if(!istrue) return false;});if(!istrue) {return false;}$('select').each(function(i,val){ var $this = $(val);istrue = validates.checkselect($this);if(!istrue) return false;});return istrue;}var validates =
