[英]Multiple forms without reloading the page
I am using php.我正在使用 php。 i need to send a post to the server every time the user sends the result of a match, without reloading the page每次用户发送匹配结果时,我都需要向服务器发送帖子,而无需重新加载页面
I've been trying jquery but I couldn't.我一直在尝试 jquery 但我做不到。
This is my form:这是我的表格:
<?php
$sqlpartidos =mysqli_query($con, "SELECT * FROM partidoprode WHERE idfecha = '$idfecha';");
while($filapartidos = mysqli_fetch_array($sqlpartidos)){
echo '<div class="list-group-item list-group-item-action flex-column ">
<div>
<div class="row justify-content-center">
<div class="col-3" id="bloqueequipo">
<div><h5 class="nombreequipos">'.$filapartidos['nombrelocal']. ' '.' </div><div><img src="'.$filapartidos['imglocal'].'" alt="" class="imgequipos"></h5></div>
</div>
<div class="col-6" id="bloqueequipo"><form id="myForm" method="post"><input type="number" id="reslocal" name="reslocal" min="0" max="10" size="1"/> - <input type="number" id="resvisitante" name="resvisitante" min="0" max="10" size="1"/><input type="hidden" name="idpartido" id="idpartido" value="'.$filapartidos['id'].'"/><input type="hidden" name="idfecha" id="idfecha" value="'.$filapartidos['idfecha'].'"/><div id="botondiv"><input type="submit" value="Submit" /></div></form> <div id="results"></div></div>
<div class="col-3" id="bloqueequipo">
<div><h5 class="nombreequipos">'.$filapartidos['nombrevisitante']. ' '.' </div><div><img src="'.$filapartidos['imgvisitante'].'" alt="" class="imgequipos"></h5></div>
</div>
</div>
</div>
<div class="col-12 text-muted nombreequipos"><small>'.$filapartidos['fecha'].'</small></div>
</div>';
}
?>
EDIT: I was trying to do this.编辑:我试图这样做。
function SubmitFormData() {
var idpartido = $("#idpartido").val();
var idfecha = $("#idfecha").val();
var reslocal = $("#reslocal").val();
var resvisitante = $("#resvisitante").val();
$.post("enviar_jugada.php", { idpartido: idpartido, idfecha: idfecha, reslocal: reslocal, resvisitante: resvisitante },
function(data) {
$('#results').html(data);
$('#myForm')[0].reset();
});
}
And the input和输入
<input type="button" id="submitFormData" onclick="SubmitFormData();" value="Submit" />
The above code is very messy and riddled with errors ( indent your code correctly will help you immensely? ) but perhaps the following approach might help?上面的代码非常混乱并且充满了错误(正确缩进你的代码会极大地帮助你吗?)但也许下面的方法可能会有所帮助?
If you use printf
or sprintf
etc you can create quite clean looking markup that has placeholders into which variables are plugged - which makes it much easier to read imo.如果您使用printf
或sprintf
等,您可以创建非常干净的标记,其中包含插入变量的占位符 - 这使得 imo 更容易阅读。 Remove All the ID attributes that you generate in the loop - you do not generally need them as you can access HTML elements using querySelector
and sibling selectors.删除您在循环中生成的所有 ID 属性 - 通常不需要它们,因为您可以使用querySelector
和同级选择器访问 HTML 元素。 In this way you can capture a (node)list of submit buttons and assign the event handler remotely rather than inline
通过这种方式,您可以捕获提交按钮的(节点)列表并远程分配事件处理程序而不是inline
The original markup is, as I say, messy so the following might not be accurate to your original intentions.正如我所说,原始标记很混乱,因此以下内容可能不符合您的初衷。
while( $filapartidos = mysqli_fetch_array( $sqlpartidos ) ){
