Two methods: 1. Use append() to add tr sub-elements, the syntax is "$("table").append("
td data ")". 2. Use appendTo(), the syntax is "$("td data ").appendTo("table");".
The operating environment of this tutorial: windows7 system, jquery1.10.2 version, Dell G3 computer.
Adding a row of data to the table is to add the tr sub-element to the table element. The following are two methods:
Method 1: append() method
append( ) method inserts content to the "end" inside the selected element.
$(A).append(B)
means inserting B at the end of A.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script src="js/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$("button").on("click", function() {
$("table").append("<tr><td>数据</td><td>数据</td></tr>");
});
});
</script>
</head>
<body class="ancestors">
<table border="1">
<tr>
<th>商品</th>
<th>价格</th>
</tr>
<tr>
<td>T恤</td>
<td>￥100</td>
</tr>
<tr>
<td>牛仔褂</td>
<td>￥250</td>
</tr>
<tr>
<td>牛仔库</td>
<td>￥150</td>
</tr>
</table><br>
<button>增加一行表格</button>
</body>
</html>
Method 2: appendTo( ) method
appendTo( ) and append( ) Although the functions of these two methods are similar, Both insert content "at the end" inside the selected element, but the operating objects of the two are reversed.
$(A).appendTo(B)
$(A).appendTo(B) means inserting A into the end of B.
<script>
$(document).ready(function() {
$("button").on("click", function() {
$("<tr><td>数据</td><td>数据</td></tr>").appendTo("table");
});
});
</script>
