巧用weui.topTips验证数据的实例

洪海洋 2019-05-09

场景一、有一个输入金额的场景,这个金额需要验证,验证说明如下:

不能为空格;

不能为0;

不能为汉字;

不能为其它字符;

不能大于200;

唯一可以的是,只有输入3~199之间的数字,下面的确定按钮才会显示,否则,隐藏这个按钮。

HTML:

场景二、所有违反规距的都有信息提示,但是“确定”按钮不隐藏,只是删除它的click事件,只有符合条件的才可以跳转

//验证
      $('input').on('blur', function() {
        var value = this.value;
        var regChinese = new RegExp("[\\u4E00-\\u9FFF]+", "g"); //汉语
        var specialSymbol =/[`~!@#$%^&*_+<>{}\/'[\]]/im; //特殊符号
        //字符串不能为空
        if(value.length == 0) {
          $('#otherPriceBtn').unbind('click');
          setTimeout(function() {
            $('.hide-description').css('display', 'block').text('不能为空,请重新输入');
          }, 500);
          //字符串是否为“空”字符即用户输入了空格
        } else if(value.replace(/(^s*)|(s*$)/g, "").length == 0) {
          $('#otherPriceBtn').unbind('click');
          setTimeout(function() {
            $('.hide-description').css('display', 'block').text('不能为空,请重新输入');
          }, 500);
          //字符串是否为空或者全部都是空格
        } else if(value == null) {
