来自每个tr的第一个td值(first td value from each tr)

来自每个tr的第一个td值(first td value from each tr)

我有下面的表格，我试过这个

$("#tablaMultas tbody tr td:first-child")

但我无法解决。

<table id="tablaMultas"> <thead> <tr> <th>Minuto inicial</th> <th>Minuto linea</th> <th>Minuto m. atras</th> <th>Valor linea</th> <th>Valor m. atras</th> <th>Minuto Espera</th> <th>Eliminar</th> </tr> </thead> <tbody style="vertical-align: text-top;" id="cuerpoTablaMultas"> <tr id="filaMulta1" style="border-top: 1px solid #E1EEF4;"> <input type="hidden" name="valoresFila" value="1-0-0-0-0-1-5"> <td>1</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>5</td> <td> <p onclick="$(&quot;#filaMulta1&quot;).remove();"> <img src="../Maestros/imagenes/borrar.png"> </p> </td> </tr> <tr id="filaMulta2" style="border-top: 1px solid #E1EEF4;"> <input type="hidden" name="valoresFila" value="2-0-0-0-0-1-5"> <td>2</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>5</td> <td> <p onclick="$(&quot;#filaMulta2&quot;).remove();"> <img src="../Maestros/imagenes/borrar.png"> </p> </td> </tr> </tbody> </table>

我需要创建一个数组，其中包含每个数据的值，在这种情况下它会[1,2]，有人可以帮助我，提前谢谢。

I have the following table shown below, I tried this

$("#tablaMultas tbody tr td:first-child")

but I cannot solve.

<table id="tablaMultas"> <thead> <tr> <th>Minuto inicial</th> <th>Minuto linea</th> <th>Minuto m. atras</th> <th>Valor linea</th> <th>Valor m. atras</th> <th>Minuto Espera</th> <th>Eliminar</th> </tr> </thead> <tbody style="vertical-align: text-top;" id="cuerpoTablaMultas"> <tr id="filaMulta1" style="border-top: 1px solid #E1EEF4;"> <input type="hidden" name="valoresFila" value="1-0-0-0-0-1-5"> <td>1</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>5</td> <td> <p onclick="$(&quot;#filaMulta1&quot;).remove();"> <img src="../Maestros/imagenes/borrar.png"> </p> </td> </tr> <tr id="filaMulta2" style="border-top: 1px solid #E1EEF4;"> <input type="hidden" name="valoresFila" value="2-0-0-0-0-1-5"> <td>2</td> <td>0</td> <td>0</td> <td>0</td> <td>0</td> <td>5</td> <td> <p onclick="$(&quot;#filaMulta2&quot;).remove();"> <img src="../Maestros/imagenes/borrar.png"> </p> </td> </tr> </tbody> </table>

and I need create a array with the value from the firts of each , in this case it would be [1,2], somebody could help me, thanks in advance.

最满意答案

尝试，

var values = $("#tablaMultas tbody").find("tr td:first-child").map(function(){ return $(this).text() }).get();

提醒：您的HTML完全无效。 Input tag cannot be a direct child of the tr 。 请参考以下演示来纠正错误，

Try,
