JS ----- JS实用小功能
1、复制页面上文字功能
function copyIdCode() { var idcode = document.getElementById("personIdcodeCopy").innerText; var oInput = document.createElement('input'); oInput.value = idcode; document.body.appendChild(oInput); oInput.select(); // 选择对象 document.execCommand("Copy"); // 执行浏览器复制命令 oInput.className = 'oInput'; oInput.style.display = 'none'; alert('复制成功'); } <p>身份证号码:<span id='personIdcodeCopy'>421023165465465498</span> <a onClick='copyIdCode()' class='value' style='color:blue;margin:20px;cursor: pointer;'>复制</a></p>
2、处理C#日期中的ticks
附件中存的是时间的ticks,在js中转成时间 new Date(parseInt((sttachmentsName[0]-621355968000000000)/10000))
因为ticks不是时间戳,不能直接用 new Date(parseInt(时间戳))
var detail = ""; var attachmentsArrys = rowdata.Attachments.split('|'); for (var i = 0; i < attachmentsArrys.length; i++) { var sttachmentsName = attachmentsArrys[i].split('_'); var url = "../upload/PassportRenewal/" + new Date(parseInt((sttachmentsName[0]-621355968000000000)/10000)).getFullYear() + "/" + attachmentsArrys[i]; if (detail == "") { detail = "<a href='" + url + "' target='_blank'>" + sttachmentsName[1] + "</a>"; }else { detail = detail + "|" + "<a href='" + url + "' target='_blank'>" + sttachmentsName[1] + "</a>"; } } return detail;
3. 弹框居中
DirectorGeneralUploadDiv为弹框的DIV的id 在显示之前调用一下这个方法
function scroll() { var a = $j(window).height(); //浏览器窗口高度 var c = $j("#DirectorGeneralUploadDiv").offset().top; //元素距离文档(document)顶部的高度 if (c > a) { $j('html,body').animate({ scrollTop: $j('#DirectorGeneralUploadDiv').offset().top }, 800); } }
4、页面滑动到指定的位置
在指位置加一个标签,调用scrollIntoView方法
<span id='fk_span'></span> function scroll(){ document.getElementById("fk_span").scrollIntoView(); }
