我使用以下代码来确保至少选中一个复选框,它会将复选框的“值”输出到名为“cont”的ID。我正在寻找一种方法来将输出转换为数组(PHP)。我不是很擅长JS。
<?php
$count = '0';
while($count <= '2') {
$count++;
$the_name = "chkBx";
$the_value = 'checkbox'.$count;
if ($count == '1') {
$its_checked = 'checked';
} else {
$its_checked = '';
}
?>
<input type="checkbox" name="<?php echo $the_name; ?>" value="<?php echo $the_value; ?>" <?php echo $its_checked; ?> >
<?php
}
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="cont"></div><!-- OUTPUTS HERE-->
<script>
$('input[type="checkbox"][name="<?php echo $the_name; ?>"]').on('change',function(){
var getArrVal = $('input[type="checkbox"][name="<?php echo $the_name; ?>"]:checked').map(function(){
return this.value;
}).toArray();
if(getArrVal.length){
//execute the code
$('#cont').html(getArrVal.toString());
} else {
$(this).prop("checked",true);
$('#cont').html("At least one value must be checked!");
return false;
};
});
</script>

更新,仍然无法从勾选到PHP变量的复选框中获取值,这就是我现在所拥有的:
<?php
$the_name = "myCheck";
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
1.<input type="checkbox" class="<?php echo $the_name; ?>" name="the_name" value="1" checked>
2.<input type="checkbox" class="<?php echo $the_name; ?>" name="the_name" value="2">
3.<input type="checkbox" class="<?php echo $the_name; ?>" name="the_name" value="3"><br/>
<span class="cont" name="bob" value="9999"></span>
<script>
function checkIt() {
var getArrVal = $(".myCheck:checked").map(function() {
return this.value;
}).get();
if (getArrVal.length) {
$('.cont').html(getArrVal.join(","));
var x=$(".cont").text();
var variablename = $(".cont").val();
} else {
$('.cont').html("At least one value must be checked!");
$(this).prop("checked", true);
getArrVal=[$(this).val()];
return false;
}
console.log(getArrVal);
}
$(function() {
$(".myCheck").on('click',checkIt);
checkIt();
});
</script>
答案 0 :(得分:0)
你需要什么阵列?
如果你这样做,你需要在加载和不允许删除复选框时继续设置它
我个人会在chekcbox上使用一个类来制作一个更短的脚本:
function checkIt() {
var getArrVal = $(".myCheck:checked").map(function() {
return this.value;
}).get();
if (getArrVal.length) {
$('#cont').html(getArrVal.join(","));
} else {
$('#cont').html("At least one value must be checked!");
$(this).prop("checked", true);
getArrVal=[$(this).val()];
return false;
}
console.log(getArrVal);
}
$(function() {
$(".myCheck").on('click',checkIt);
checkIt();
});
