日常用的css基础和自己常用的js封装

JS基础:
(function($){ //$.fn.extend({}) 对象实例来调用此方法 $("").方法名() $.fn.extend({ /* 剩余输入字数 num:要输入的字数总个数 * eg:$(".length100").getTextLen(100) * $(".length100").getTextLen(1000) * */ getTextLen: function(num) { var _num = num; var timer = null; $(this).on('mouseover', function() { clearInterval(timer); $(this).attr('maxLength', _num); var _this = $(this); timer = setInterval(function() { var thisVal = _this.val(); if (thisVal.length > _num) { thisVal = thisVal.substring(0, _num); _this.val(thisVal); } _this.parent().find('.leng').text(thisVal.length); }, 30); }); $(this).mouseover(); }, }); //$.extend({}) 直接用jQuery类即可引用 $.方法名() $.extend({ /* * *提示框, *目前三个参数 txt:要显示的文本;times:自动关闭的时间(不设置的话默认1500毫秒) status:状态, *eg: $.showTips('请输入文本提示'); $.showTips('提交成功~ 即将进入下一步',1500,1); * */ showTips:function(txt,times,status){ var showHtml = ""; if(txt != ""){ if(status == 1 && status !=undefined){ console.info("1111"); showHtml = '<div class="tipsBox t-c-f white">'+ '<div class="bgcolok tipub"><img src="images/ok.png" alt="OK" />'+txt+'</div>'+ '</div>'; }else if(status == 2){ showHtml = '<div class="tipsBox t-c-f white">'+ '<div class="bgcolerror tipub"><img src="images/error.png" alt="error" />'+txt+'</div>'+ '</div>'; console.info("222"); }else{ showHtml = '<div class="tipsBox t-c-f white">'+ '<div class="bgcolwarn tipub"><img src="images/warn.png" alt="warn" />'+txt+'</div>'+ '</div>'; console.info("other"); } } $("body").prepend(showHtml); if(times == "" || times == undefined){ //默认消失时间 1.5s times = 1500; } setTimeout(function(){ $(".tipsBox").remove(); },times) }, /* * 常用正则 * eg: $.方法名() * */ //手机号

return isMobile.test(p) ? true : false;

//邮箱

//身份证
}) })(jQuery); /* * Img:要放图片的img元素,onload时传参可用this * maxHeight :img元素的高度,像素(图片框 最大高度) * maxWidth:img元素的宽度,像素(图片框 最大宽度) * eg: <img src="" onload="AutoResizeImage(this,250,300)"/> * */ function AutoResizeImage(Img, maxWidth, maxHeight) { var image = new Image(); //原图片原始地址(用于获取原图片的真实宽高,当<img>标签指定了宽、高时不受影响) image.src = Img.src; // 当图片比图片框小时不做任何改变 if (image.width < maxWidth&& image.height < maxHeight) { Img.width = image.width; Img.height = image.height; } else{ //原图片宽高比例 大于 图片框宽高比例,则以框的宽为标准缩放,反之以框的高为标准缩放 if (maxWidth/ maxHeight <= image.width / image.height) { //原图片宽高比例 大于 图片框宽高比例 Img.width = maxWidth; //以框的宽度为标准 Img.height = maxWidth* (image.height / image.width); } else { //原图片宽高比例 小于 图片框宽高比例 Img.width = maxHeight * (image.width / image.height); Img.height = maxHeight ; //以框的高度为标准 } } } /* * 图片比例缩放 * eg: <img src="" onload="scalingImg(this)"/> * */ /*function scalingImg(obj){ var $this = $(obj); var imgWidth=$this.width(); var imgHeight=$this.height(); var parent = $this.parent(); var containerWidth = parent.width(); var containerHeight=parent.height(); var containerRatio = containerWidth / containerHeight; var imgRatio = imgWidth / imgHeight; if (imgRatio > containerRatio) { imgWidth = containerWidth; imgHeight = containerWidth / imgRatio; } else if (imgRatio < containerRatio) { imgHeight = containerHeight; imgWidth = containerHeight * imgRatio; } else { imgWidth = containerWidth; imgHeight = containerHeight; } $this.attr('width',imgWidth); $this.attr('height',imgHeight); }*/ /* * * tab切换 * eg: * */ function setTab(name,cursel,n){ for(i=0;i<=n;i++){ var menu=document.getElementById(name+i); var con=document.getElementById("con"+name+i); if(menu == null || con == null)continue; menu.className=i==cursel?"hover":""; con.style.display=i==cursel?"block":"none"; } }
用JQuery实现选中select里面的option显示对应的div
HTML:
<select class="span9 m-wrap j-pactchoose" name="pactkind">
<option value="1">标准无价易制毒合同</option>
<option value="2">标准有价易制毒合同</option>
<option value="3">非标准无价易制毒合同</option>
<option value="4"></option>
</select>
<div>
<div id="div1">内容一</div>
<div id="div2 " style="display:none">内容二</div>
<div id="div3" style="display:none">内容三</div>
<div id="div4" style="display:none">Not Thing</div>
</div>
$(".j-pactchoose").on('change',function(){
var i = $(this).find("option:selected").val();
if($("#pressDrug"+i).length == 1){
$("#pressDrug"+i).show().siblings(".opt-lessdrug").hide()
}else{
$(".opt-lessdrug").hide()
}
})
