我在表格行(tr)中选择了选项字段和自由输入字段。 当我选择一些选项时,该领域会感觉到ajax。
当我添加新行时,我想感觉输入字段是新行而不是第一行。
是表格html代码:
<table class="table table-bordered" id="tbl1">
<tr id="rowId">
<td>
<select class="form-control" onchange="fetch_select(this.value)">
<option></option>
<?php
$conn = mysqli_connect('localhost','root','','trailers');
$query = "SELECT * FROM trailers";
$run = mysqli_query($conn,$query);
while($row = mysqli_fetch_array($run)){
$id = $row[0];
echo '<option value="'.$id.'">'.$id.'</option>';
}
?>
</select>
</td>
<td><input type="text" name="text" class="form-control" placeholder="Movie Name" value="" readonly></td>
</tr>
</table>
我的Java脚本代码
function fetch_select(val){
$.ajax({
type: 'post',
url: 'rs.php',
data: {
get_option:val
},
success: function (response) {
document.getElementById("rowId").innerHTML=response;
}
});
}
添加/删除java脚本代码:
$(document).ready(function(){
var cnt = 2;
var a = '<?php $query = "SELECT * FROM trailers";
$run = mysqli_query($conn,$query);
while($row = mysqli_fetch_array($run)){
$id = $row[0];
echo "<option>".$id."</option>";
}?>';
$("#anc_add").click(function(){
$('#tbl1 tr').last().after('<tr><td></td><td><input type="text" name="text" class="form-control" placeholder="Movie Name" value="" readonly></td></tr>');
$('#tbl1 tr:last-child td:first').append('<select class="form-control" onchange="fetch_select(this.value)"><option></'+a+'</select>');
cnt++;
});
$("#anc_rem").click(function(){
if($('#tbl1 tr').size()>1){
$('#tbl1 tr:last-child').remove();
}else{
alert('One row should be present in table');
}
});
});
这是我的rs.php
<?php
$conn = mysqli_connect('localhost','root','','trailers');
$req = $_POST['get_option'];
if(isset($req)){
$query = "SELECT * FROM trailers WHERE id = '$req'";
$run = mysqli_query($conn,$query);
while($row = mysqli_fetch_array($run)){
$nm = $row[1];
echo '<tr>';
echo '<td><select class="form-control" readonly></select></td>';
echo '<td><input type="text" class="form-control" name="text" value="'.$nm.'"></td>';
echo '</tr>';
exit;
}
}
