<textarea id="area" name="ss" placeholder="请输入文本内容" rows="10" cols="50" onkeydown=‘inputLimit(this,1,2000);‘ onkeyup=‘inputLimit(this,1,2000);‘></textarea> <script type="text/javascript"> /*字数限制*/ function inputLimit(field, type, maxlimit) { if (type == 1) { if (field.value.replace(/[^\x00-\xff]/g, "xx").length > maxlimit) { alert("输入字数已达上项"); var str = ""; var n = 0; var schar; for (var i = 0; schar = field.value.charAt(i); i++) { n += (schar.match(/[^\x00-\xff]/) != null ? 2 : 1); if (n > maxlimit) break; str += schar; } field.value = str; } } } </script> 　注:onkeyup和onkeydown需要同时使用

昨天把系分的项目又加了一点逻辑判断，比如已经下单的菜品不能减少，不能重复下单，应该先下单再支付等… 弄完购物车的逻辑之后，发现一直没有管备注那一块，于是输入了一下试试，结果发现不能换行…就非常丑陋 后来查阅相关资料发现，我用的wxml组件是 input ，只能 单行输入 ，如果要支持 多行输入 ，应该用 textarea 。 下面就来介绍一下 textarea ： 属性名 类型 默认值 说明 最低版本 value String 输入框的内容 placeholder String 输入框为空时占位符 placeholder-style String 指定 placeholder 的样式 placeholder-class String textarea-placeholder 指定 placeholder 的样式类 disabled Boolean false 是否禁用 maxlength Number 140 最大输入长度，设置为 -1 的时候不限制最大长度 auto-focus Boolean false 自动聚焦，拉起键盘。 focus Boolean false 获取焦点 auto-height Boolean false 是否自动增高，设置auto-height时，style.height不生效 fixed Boolean false 如果 textarea 是在一个
