使用js动态添加组件

2022-11-06 12:42:04

在文章开始之前,我想说两点

1 自己初学js,文章的内容在大神看来可能就是不值一提,但是谁都是从hello world来的,望高手不吝指教#

2 我知道这个标题起的比较蛋疼,大家看图就能说明问题:

初始页面如下图:

点击"有"后,如下图:

点击"点此添加条目"两次后,如下图:

OK,我们分析代码:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%System.out.println(request.getContextPath()); %>
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
		<title>新建慢病档案</title>
		<link rel="stylesheet" type="text/css" href="../../../css/styles.css" />

		<script type="text/javascript" src="../../../js/jquery1.7.js"></script>

		<script type="text/javascript" src="js/familyHistoryXs.js"></script>

		</head>

	<body>

	<s:form action="xx" method="post" theme="simple" >
	<div align="center" id="div_main">
		<table class="tab_head" width="100%">
			<tr>
				<td>
					<h2 align="center">使用js动态添加条目</h2>
				</td>

			</tr>
		</table>

		<br/>

						<div class="tab_content">
						<div  class="subTabs" >
						<br/>

						<div id="family"  class="subTabs">

							<table class="tab_frm" width="100%">
								<tr>
									<td class="left" width="30%">
										有无其他条目：
									</td>
									<td>

										<a id="a_family" style="display:none" href='#' onclick="addFamily();return false;">点此添加条目</a>
								  </td></tr></table>

							<table class="tab_frm" width="100%" style="display:none;"  id="familyHistory">
								<tr >
									<td class="left" width="10%" rowspan="2">
										与本人关系：<s:select  list="#{'-1':'-请选择-','父亲':'父亲','母亲':'母亲','哥哥':'哥哥','弟弟':'弟弟','姐姐':'姐姐','妹妹':'妹妹','儿子':'儿子','女儿':'女儿'}" theme="simple"/></td>
									<td class="left" width="15%" >所患疾病</td>
									<td width="15%"><input type="checkbox"  value="高血压"  onclick="familyTime(this)">高血压

									<td width="15%"><input type="checkbox"  value="糖尿病"  onclick="familyTime(this)">糖尿病

									<td width="15%"><input type="checkbox"  value="冠心病"  onclick="familyTime(this)">冠心病

										</td>

								</tr>
								<tr>
									<td class="left" width="15%">备注(如患其他疾病请填写)</td>
									<td width="75%" colspan="5"><s:textarea theme="simple"  cssStyle="width:97%;overflow-y:visible;" /></td>
								</tr>
							</table>
							<br/><br/>
						</div>

						</div>
						</div>

		<input type="button" name="back" value="上一步"
		onclick="javascript:window.location.href='findMedicalHistory.action'">
		<input type="submit" value="下一步"   id="submitInfo"/>

	</div>
	</s:form>
	</body>
</html>

html引入了familyHistoryXs.js,我们进去看看

/**
 *
 */
var familyCount;

$(document).ready(function(){
	familyCount=0;

	//给所有name为family的input上绑定事件 click
	//一旦触发了 就去运行radioEvent方法
	$("input[name='family']").bind("click",function(){
		radioEvent($(this));
	});
});

function radioEvent(e) {

	//a_family默认的diplay是none 也就是不显示
	//如果我点击了yes 就让它显示
	//#a_family 就是网页里那个  点此添加条目 的东西

	//如果点击 无 首先隐藏 点此添加条目
	//接着下面的条目也祛除掉

	if ("yes" == e.val()) {
		$("#a_family").attr("style", "display:''");
	} else {
		$("#a_family").attr("style", "display:none");
		for ( var i = 0; i < familyCount; i++) {
			$("#familyHistory" + i).remove();
		}
		familyCount = 0;
	}

}

function addFamily(){
    var tr=$("#familyHistory").clone();
    tr.attr("id","familyHistory"+familyCount);
    tr.attr("style","display:'';margin-top:10px");

	$("#family").append(tr);

	var select=tr.find("select").eq(0);
	select.attr("name","fimalyList["+familyCount+"].patientRelation");
	select.attr("id","fimalyList["+familyCount+"].patientRelation");

	var gxy=tr.find("input").eq(0);
	gxy.attr("name","fimalyList["+familyCount+"].gxy");
	gxy.attr("id","fimalyList["+familyCount+"].gxy");

	var tnb=tr.find("input").eq(1);
	tnb.attr("name","fimalyList["+familyCount+"].tnb");
	tnb.attr("id","fimalyList["+familyCount+"].tnb");

	var gxb=tr.find("input").eq(2);
	gxb.attr("name","fimalyList["+familyCount+"].gxb");
	gxb.attr("id","fimalyList["+familyCount+"].gxb");

	var note=tr.find("textarea").eq(0);
	note.attr("name","fimalyList["+familyCount+"].note");
	note.attr("id","fimalyList["+familyCount+"].note");

	familyCount++;

}
