前端相关校验

1,文本框失去焦点时若有值则trim

$('#identityTF').blur(function (e) {
            console.log('blur');
            //去掉首尾的空格
            var eventTarget = e.srcElement || e.target || e.toElement;
            if (eventTarget) {
                var identityTmp = eventTarget.value;
                identityTmp = util.trim(identityTmp);
                if (identityTmp) {
                    eventTarget.value = identityTmp;
                }
            }
})

 

 

2,文本框聚焦或有键按下时清除错误样式

/***
         * 清除错误样式
         * @param event
         */
        var cleanErrorStyle = function (event) {
            var errorClass = 'has-error-inp';
            var eventTarget = event.srcElement || event.target || event.toElement;
            $(eventTarget).removeClass(errorClass);
        };
        $('input[type=text]').keydown(cleanErrorStyle).focus(cleanErrorStyle);

 

 

 

 

3,如何在事件处理方法中获取事件源(控件)

方式一:

var eventTarget = e.srcElement || e.target || e.toElement;

方式二:

var val=$(this).val();
