我想要一个HTML表格,我只能选择一个单元格并检索它的值,以便我可以在我的应用程序的其他操作中使用。问题是我不知道如何以一种只能选择一个单元格,所选单元格改变它的颜色等方式构造表格。这是一个例子,所以你们可以想象我的想法。
这是我的应用程序的硬编码模型:

我在第一个截图中需要基本相同的东西。如果有人可以在一些帮助下启发我,我会很感激。提前谢谢。

给出一个id并使用getElementById()来选择单元格。不要使用中心标签,将其展开。我假设你想使用javascript
答案 1 :(得分:0)
试试这样。我正在警惕地给予价值。您可以在变量中指定值并在应用中使用。 html表是你的一个,我只是在表中添加了一个id。和一个css课程“活跃”#39;高亮点击点击div。 (您需要在页面中包含jquery脚本)
$(document).ready(function(){
$(document).on('click','.mytable tbody tr td',function(){
$(this).addClass('active');
$(this).parents('tbody').find('td').not(this).removeClass('active');
alert($(this).find('strong').html());
});
});
&#13;
.active{
background: #999;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

答案 2 :(得分:0)
如果你有
<td id="cell1"></td>
然后在jQuery中
$(function() { //this wrapper just tells the script not to run until the whole page is rendered
$("#cell1").click(function(event) { //this bit handles any user clicks on cell1
console.log("clicked cell 1");
});
});
只要用户单击它,就会登录到浏览器控制台。
如果您想为多个单元格运行相同的事件,请为它们提供所有类别,然后选择相反(例如<td class="myGroup">
和$(".myGroup").click(...
)。
这一切都使用标准的jQuery语法来绑定到浏览器事件 - 可能值得一读它的基础知识。
答案 3 :(得分:0)
这个答案假设您希望通过单击表格单元格从表格中获取值。
对于jQuery,我将使用委托方法向表的所有单元格添加单击处理程序。通过使用delegated方法,您可以将更少的点击处理程序附加到页面,如果您以后动态向表中添加单元格(即Ajax),它也会起作用。
单击“代码片段”中的表格单元格,将其值复制到绿色框中。
var $display = $('.display');
$('.my-table').on('click', 'td', function(e) {
$display.text(this.innerHTML);
});
.display {
width: 200px;
margin: 1rem 0;
padding: 0.5rem 1rem;
border: 1px solid green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table class="my-table">
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
<tr>
<td>Aaron</td>
<td>Anderson</td>
<td>1</td>
</tr>
<tr>
<td>Beth</td>
<td>Black</td>
<td>2</td>
</tr>
</table>
<div class="display"></div>
注意:正如其他人所说,<center>
tag is depreciated。请改用text-align
。

$("#cell1").click(function(){
$(this).css("background-color", "#ccc");
});
