篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了jQuery怎样判断按钮是不是被选中相关的知识,希望对你有一定的参考价值。
if($('#xy_checkbox').is(':checked'))//如果被选中
else
//未选中
参考技术A 建议你下一个手册,先看一遍
表单对象属性:
:checked
匹配所有选中的被选中元素(复选框、单选框等,不包括select中的option)
$("input:checked")
我如何使用jquery检查单选按钮是不是被选中[重复]
【中文标题】我如何使用jquery检查单选按钮是不是被选中[重复]【英文标题】:How do i check a radio button is checked or not using jquery [duplicate]我如何使用jquery检查单选按钮是否被选中[重复] 【发布时间】:2017-08-25 17:40:40 【问题描述】:如何使用 jquery 检查单选按钮是否被选中???
代码如下:
function handlesClick(myRadio)
debugger
var selectedmerchant = [];
if (myRadio != '')
var myRadios = $('input[name=myRadio]');
//var checkedValue = $("#myRadio").attr('checked', 'checked');
//if ($('#myRadio').is(':checked')) alert("it's checked");
//$('input[type="radio"][class="icheck-list"]:checked').val()
if ($("#myRadio").is(":checked") === true)
selectedmerchant.push(myradio);
selectedmerchant.join(",");
else
var index = selectedmerchant.indexof(merchant);
selectedmerchant.splice(index, 1);
//if (document.getelementbyid(myradio).checked == true)
// selectedmerchant.push(myradio);
// selectedmerchant.join(",");
//
//else
// var index = selectedmerchant.indexof(merchant);
// selectedmerchant.splice(index, 1);
//
我想检查复选框是否被选中,以便我可以使用 javascript 在数组中推送或切片。 任何代码???

【问题讨论】:
不工作这就是我问男人的原因 显示一些相关的html 这可能意味着你的代码没有被正确调用 我已经用html编辑了.. 格式化你的html和js) 【参考方案1】:检查一下,
window.selectedmerchant = ;
function handlesClick(myRadio)
if ($(myRadio).is(":checked"))
window.selectedmerchant[$(myRadio).attr("name")] = $(myRadio).attr("id");
console.log(window.selectedmerchant);

我只举了三个例子作为演示,但检查代码,它现在工作正常。
我希望这会有所帮助。
【讨论】:
【参考方案2】:为此,请尝试以下代码:
<input name="3" onclick="handlesClick(this);" id="3_1" type="radio">Agree
<input name="3" onclick="handlesClick(this);" id="3_2" type="radio">Disagree
// 这里是JS代码 //
function handlesClick(RadioId)
if (RadioId != '')
if ($(RadioId).is(":checked") === true)
//Add condition for checked Radio
else
//Add condition for unchecked Radio
