1、提取公共方法common.js
function $(key){if(key){if(key.startsWith("#")){key = key.substring(1)return document.getElementById(key)}else{let nodeList = document.getElementsByName(key)return Array.from(nodeList)}}
}
2、 给库存名称添加超链接
2.1、index.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><link rel="stylesheet" href="style/index.css"><script src="script/axios.min.js"></script><script src="script/index.js"></script><script src="script/common.js"></script>
</head>
<body><div id="div0"><div id="div_title"><p>欢迎使用水果库存系统</p></div><div id="div_fruit_table"><table id="fruit_tbl"><tr><th class="w25">名称</th><th class="w25">单价</th><th class="w25">库存</th><th>操作</th></tr><!--<tr><td><a href='edit.html?fid=1'>苹果</a></td><td>5</td><td>100</td><td><img class="delImg" src="imgs/del.png" onclick='delFruit(1)'/></td></tr>--></table></div></div>
</body>
</html>
2.2、index.js
window.onload=function(){loadData();
}
loadData=function(){axios({method:'get',url:'/index'}).then(response=>{debuggerlet fruitList = response.data.data// 此处使用的是axios，那么响应回来的数据自动就是json，// 不需要再进行parse(如果是原始的ajax操作，那么一定需要parse)// let fruitArr = JSON.parse(fruitList)let fruitArr = fruitListfor(let i = 0 ; i<fruitArr.length; i++){let fruitTbl = $("#fruit_tbl")let tr = fruitTbl.insertRow()let fnameTD = tr.insertCell()let priceTD = tr.insertCell()let fcountTD = tr.insertCell()let operTD = tr.insertCell()let fruit = fruitArr[i]//fnameTD.innerText = fruit.fnamefnameTD.innerHTML = '<a href="edit.html?fid='+fruit.fid+'">'+fruit.fname+'</a>';priceTD.innerText = fruit.pricefcountTD.innerText = fruit.fcountoperTD.innerHTML="<img class=\"delImg\" src=\"imgs/del.png\"/>"}})
}
3、创建编辑水果库存页面edit.html
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><link rel="stylesheet" href="style/index.css"><script src="script/axios.min.js"></script><script src="script/edit.js"></script><script src="script/common.js"></script>
</head>
<body>
<div id="div0"><div id="div_title"><p>编辑水果库存信息</p></div><div id="div_fruit_table"><input type="hidden" id="fid" value="0"/><table id="fruit_tbl"><tr><th class="w25">名称:</th><td><input type="text" id="fname"/></td></tr><tr><th class="w25">单价:</th><td><input type="text" name="price" id="price"/> </td></tr><tr><th class="w25">库存:</th><td><input type="text" name="fcount" id="fcount"/> </td></tr><tr><th class="w25">备注:</th><td><input type="text" name="remark" id="remark"/> </td></tr><tr><th colspan="2"><input type="button" value="修改" onclick="update()"/><input type="button" value="取消"/></th></tr></table></div>
</div>
</body>
</html>
4、获取URL参数中的queryString查询字符串edit.js
let queryString = window.location.search.substring(1)
