Question

我想将数组表单传递给JavaScript，然后传递给AJAX。这是表格：

<form>
	<?php
	       $c=$_POST['sweater'];
		foreach ($c as $sid){
			echo $sid;
			$query1="select * from `usersweater` where `Sweaterid`='$sid'";
			$result1=mysql_query($query1);
			$row1=mysql_fetch_assoc($result1);
			$sweaternikname=$row1['SNickname'];
			$sweaterpic=$row1['Sweaterpic'];
			echo $sweaterpic;
	?>

	<div style=" ">
		<ul class="sweaters">
			<li> <h4><?php echo $sweaternikname; ?></h4> <img src="upload/<?php echo $sweaterpic; ?>"> </li>
		</ul>
	</div>
	

					<!-------requester's own sweater details--------------->
	<input type="hidden" name="sid[]" value="<?php echo $sid;?>">
	<?php } ?>
        <div style="float:right; margin-right:10px;">
		<input type="submit" name="next" onclick="ajaxFunction()" value="NEXT" class="btn woo_btn btn-primary">
		<input type="button" name="cancel" value="CANCEL" class="btn woo_btn btn-primary">
		</div>
</form>

这是脚本：

<script language="javascript" type="text/javascript">
function ajaxFunction(){
	var ajaxRequest;  // The variable that makes Ajax possible!
	try{
		ajaxRequest = new XMLHttpRequest();
	} catch (e){

		try{
			ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
		} catch (e) {
			try{
				ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
			} catch (e){

				alert("Your browser broke!");
				return false;
			}
		}
	}
	ajaxRequest.onreadystatechange = function(){
		if(ajaxRequest.readyState == 4){
			var ajaxDisplay = document.getElementById('ajaxDiv');
			ajaxDisplay.innerHTML = ajaxRequest.responseText;
		}
	}
var elements = document.getElementsByName('sid[]');  
}
ajaxRequest.open("POST","Usercloset2.php" ,true);
ajaxRequest.setRequestHeader("Content-type","application/x-www-form-urlencoded");
ajaxRequest.send(elements);
}
</script>

如何以数组的形式发送sid []，以便我可以使用上一页中使用的这个数组？

Answer 1

您可以创建查询字符串并像

一样发送

function ajaxFunction() {
    var ajaxRequest; // The variable that makes Ajax possible!
    try {
        ajaxRequest = new XMLHttpRequest();
    } catch (e) {

        try {
            ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {

                alert("Your browser broke!");
                return false;
            }
        }
    }
    ajaxRequest.onreadystatechange = function () {
        if (ajaxRequest.readyState == 4) {
            var ajaxDisplay = document.getElementById('ajaxDiv');
            ajaxDisplay.innerHTML = ajaxRequest.responseText;
        }
    }
    var elements = document.getElementsByName('sid[]');
    var params = [];
    for (var i = 0; i < elements.length; i++) {
        params.push(elements[i].name + '=' + encodeURIComponent(elements[i].value))
    }

    ajaxRequest.open("POST", "Usercloset2.php?" + params.join('&'), true);
    ajaxRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    ajaxRequest.send();
}

Answer 2

首先，您必须将变量声明为数组类型，如下所示

var elements=[];

然后使用下面的代码

从输入字段中获取值

elements=document.getElementsByName('sid');

然后将其传递给你。

希望这能解决你的问题
