哈哈 手工馒头好吃，今天小编跟大家分享手工js表单验证代码，感兴趣的朋友快来吧。

因为是自定义样式，所以兼容所有浏览器版本，个人认为非常漂亮：网址wuxi.rongzi.com

css

<style> .ui-slider-tooltip{ background:#fa; border:px solid #fa; color:#fff; display: block; text-align: left; padding: px px px px; position: absolute; z-index:; } .ui-corner-all { border-radius: px; -moz-border-radius-bottomleft:px; -moz-border-radius-bottomright:px; -moz-border-radius-topleft:px; -moz-border-radius-topright:px; -webkit-border-top-left-radius:px px; -webkit-border-top-right-radius:px px;-webkit-border-bottom-right-radius:px px; -webkit-border-bottom-left-radius:px px;} .ui-tooltip-pointer-down { border-bottom-width: ; border-left: px dashed transparent; border-right: px dashed transparent; border-top: px solid #fa; bottom: -px; display: block; height:; left: %; margin-left: -px; position: absolute; width:;} .ui-tooltip-pointer-down-inner { border-left: px dashed transparent; border-right: px dashed transparent; border-top: px solid #fa; left: -px; top: -px; position: absolute; } .tip{ font-size:pt; line-height:px;} .error{ border: px solid rgb(, , );} </style>

前台：

<input type="text" id="userName"/> <input type="submit" onclick="submitOneClickApply()"/>

js:

function submitOneClickApply() { var username = $("#userName").val(); if (username == "" || username == "请输入您的姓名") { $("#userName").rzAlertTips({ flagInfo: '请输入联系人', isAnimate: true }); }

调用的js:

<script type="text/javascript"> (function ($) { jQuery.fn.extend({ rzAlertTips: function (settings) { $(this).each(function () { //初始化配置信息 var options = jQuery.extend({ flagCss: "tip", flagWidth: $(this).outerWidth(), flagInfo: $(this).attr("title"), isAnimate: false }, settings); if (!options.flagInfo) { return; } $(this).removeAttr("title"); var obj = $(this); var oToolTip = null; var fun_show = function () { //设置提示信息最小宽度为 options.flagWidth = "auto"; // (parseInt(options.flagWidth) < ) ? : parseInt(options.flagWidth);+ "px" var oTip = $("<div class='ui-slider-tooltip ui-corner-all' id='tipWrap_" + $(this).attr("id") + "'></div>"); var oPointer = $("<div class='ui-tooltip-pointer-down'><div class='ui-tooltip-pointer-down-inner'></div></div>"); var oTipInfo = $("<div>" + options.flagInfo + "</div>").attr("class", options.flagCss).css("width", options.flagWidth); //合并提示信息 oToolTip = $(oTip).append(oTipInfo).append(oPointer); if ($("#tipWrap_" + $(this).attr("id")).length > ) $("#tipWrap_" + $(this).attr("id")).remove(); //添加淡入效果 if (options.isAnimate) { $(oToolTip).fadeIn("slow"); } $(obj).after(oToolTip); //计算提示信息的top、left和width //position.top var position = $(obj).position(); var oTipTop = eval(position.top - $(oTip).outerHeight() - ); var oTipLeft = position.left; $(oToolTip).css("top", oTipTop + "px").css("left", oTipLeft + "px"); }; fun_show(); $('.error').removeClass('error'); $(this).addClass("error"); setTimeout(function () { $(oToolTip).remove(); }, ); }); return this; } })(jQuery); </script>

以上内容就是小编给大家分享的纯手写漂亮的表单验证，希望大家喜欢。
