使用JavaScript动态添加/删除表行
我正在尝试在和之后添加/删除表行 这是我的密码: HTML表单使用JavaScript动态添加/删除表行,javascript,html,Javascript,Html,我正在尝试在和之后添加/删除表行 这是我的密码: HTML表单 <div id="POItablediv"> <input type="button" id="addPOIbutton" value="Add POIs"/><br/><br/> <table id="POITable" border="1"> <tr> <td>POI</td>
<div id="POItablediv">
<input type="button" id="addPOIbutton" value="Add POIs"/><br/><br/>
<table id="POITable" border="1">
<tr>
<td>POI</td>
<td>Latitude</td>
<td>Longitude</td>
<td>Delete?</td>
<td>Add Rows?</td>
</tr>
<tr>
<td>1</td>
<td><input size=25 type="text" id="latbox" readonly=true/></td>
<td><input size=25 type="text" id="lngbox" readonly=true/></td>
<td><input type="button" id="delPOIbutton" value="Delete" onclick="deleteRow(this)"/></td>
<td><input type="button" id="addmorePOIbutton" value="Add More POIs" onclick="insRow()"/></td>
</tr>
</table>
</div>
现在,如您所见,在我的表中有文本字段和按钮。我想要的是:
有人能帮我吗 您只需克隆具有输入的第一行,然后获取嵌套输入并更新其ID以添加行号(并对第一个单元格执行相同操作) 下面是演示
函数deleteRow(行){
var i=row.parentNode.parentNode.rowIndex;
document.getElementById('POITable').deleteRow(i);
}
函数insRow(){
console.log('hi');
var x=document.getElementById('POITable');
var new_row=x.rows[1]。克隆节点(true);
var len=x.rows.length;
新的行。单元格[0]。innerHTML=len;
var inp1=new_row.cells[1]。getElementsByTagName('input')[0];
inp1.id+=len;
inp1.value='';
var inp2=new_row.cells[2].getElementsByTagName('input')[0];
inp2.id+=len;
inp2.value='';
x、 追加子项(新的_行);
}
POI
纬度
经度
删除?
添加行?
1.
这似乎比上面的答案更清楚
<script>
var maxID = 0;
function getTemplateRow() {
var x = document.getElementById("templateRow").cloneNode(true);
x.id = "";
x.style.display = "";
x.innerHTML = x.innerHTML.replace(/{id}/, ++maxID);
return x;
}
function addRow() {
var t = document.getElementById("theTable");
var rows = t.getElementsByTagName("tr");
var r = rows[rows.length - 1];
r.parentNode.insertBefore(getTemplateRow(), r);
}
</script>
<table id="theTable">
<tr>
<td>id</td>
<td>name</td>
</tr>
<tr id="templateRow" style="display:none">
<td>{id}</td>
<td><input /></td>
</tr>
</table>
<button onclick="addRow();">Go</button>
var-maxID=0;
函数getTemplateRow(){
var x=document.getElementById(“templateRow”).cloneNode(true);
x、 id=“”;
x、 style.display=“”;
x、 innerHTML=x.innerHTML.replace(/{id}/,++maxID);
返回x;
}
函数addRow(){
var t=document.getElementById(“theTable”);
var rows=t.getElementsByTagName(“tr”);
var r=行[rows.length-1];
r、 parentNode.insertBefore(getTemplateRow(),r);
}
身份证件
名称
{id}
去
1&2:innerHTML可以接受HTML和文本。你可以这样做:
c1.innerHTML=“”代码>
可能是也可能不是最好的方法,但你可以这样做
3:我只需要使用一个全局变量来保存POI的数量,并每次递增/递减它。Easy Javascript使用删除功能添加更多行
