我有一个使用JQuery的示例程序
我在使用数据属性添加新表行时出现问题,应该在按钮之前或表行中显示。
JS:
var newhtml = '<table><tr><td>data1</td><td>data2</td><td>data3</td></tr><!--show here--><!--new table row added in clicking more--><tr><td></td><td></td><td><button>more</button></td></tr></table>';
$(".advanced-info").click(function(){
console.log($("#" + $(this).attr("data-div")).html().length);
if ($("#" + $(this).attr("data-div")).html().length > 0) {
$("#" + $(this).attr("data-div")).empty();
} else {
$("#" + $(this).attr("data-div")).append(newhtml);
}
});
输出
我道歉我的问题不明确

你走了:
我已将.attr的用法更改为.data。
var newhtml = '<table><tr><td>data1</td><td>data2</td><td>data3</td></tr><tr><td></td><td></td><td><button>more</button></td></tr></table>';
$(".advanced-info").click(function() {
console.log($("#" + $(this).attr("data-div")).html().length);
if ($("#" + $(this).data("div")).html().length > 0) {
$("#" + $(this).data("div")).empty();
} else {
$("#" + $(this).data("div")).append(newhtml);
}
});

试试这种方式。
public partial class Form1 : Form
{
SerialComm arduino = new SerialComm();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
//Arduino
arduino.InitialiseSerial();
String[] portList = arduino.portList;
foreach (String COM in portList)
{
comboBox1.Items.Add(COM);
}
if (portList.Length > 0)
{
comboBox1.SelectedItem = comboBox1.Items[0];
}
else
{
comboBox1.Text = "No microcontroller found!";
}
}
private void button1_Click(object sender, EventArgs e)
{
arduino.StartMC(serialPort1, comboBox1.SelectedItem.ToString());
//as the DataReceived never fires arduino.receivedData stays null
if (arduino.receivedData != null)
{
for (int i = 0; i < 101; i++)
{
textBox1.AppendText(arduino.receivedData);
}
}
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
arduino.CloseMC();
}
}
var newhtml = '<table><tr style="display:none;"><td>data1</td><td>data2</td><td>data3</td></tr><tr><td></td><td></td><td><button>more</button></td></tr></table>';
$(".advanced-info").click(function() {
console.log($("#" + $(this).attr("data-div")).html().length);
if ($("#" + $(this).attr("data-div")).html().length > 0) {
$("#" + $(this).attr("data-div")).empty();
} else {
$("#" + $(this).attr("data-div")).append(newhtml);
}
});
$("div").on("click", "button", function() {
$(this).closest("table").find("tr:eq(0)").css("display", "table-row");
$(this).hide();
});
希望这是你的需要!
