关于Jquery反复选中单选框无效问题
需求:系统默认选项为“是”的情况下,不能够编辑并且不能够删除。也就是说当选择选“系统默认”项的值为“是”时,“允许编辑”和“允许删除”项的值默认为“否”。
问题原因:在点击不同的“系统默认”单选按钮选项的时候,在change事件中根据当前控件选中值,改变“允许编辑”和“允许删除”项的单选框默认选中值,反复操作,每个单选框只有第一次选择才会有效。
Html代码如下:
<div class="form-group row">
<label class="col-sm-2 col-form-label text-right">系统默认:</label>
<div class="col-sm-10 row m-auto">
<div class="radio radio-success">
<input type="radio" id="IsSystem_1" value="1" name="IsSystem">
<label for="IsSystem_1">是</label>
</div>
<div class="radio radio-danger">
<input type="radio" id="IsSystem_0" value="0" name="IsSystem" checked>
<label for="IsSystem_0">否</label>
</div>
</div>
</div>
<div class="form-group row">
<label class="col-sm-2 col-form-label text-right">允许编辑:</label>
<div class="col-sm-4 row m-auto">
<div class="radio radio-success">
<input type="radio" id="AllowEdit_1" value="1" name="AllowEdit" checked>
<label for="AllowEdit_1">是</label>
</div>
<div class="radio radio-danger">
<input type="radio" id="AllowEdit_0" value="0" name="AllowEdit">
<label for="AllowEdit_0">否</label>
</div>
</div>
<label class="col-sm-2 col-form-label text-right">允许删除:</label>
<div class="col-sm-4 row m-auto">
<div class="radio radio-success">
<input type="radio" id="AllowDelete_1" value="1" name="AllowDelete" checked>
<label for="AllowDelete_1">是</label>
</div>
<div class="radio radio-danger">
<input type="radio" id="AllowDelete_0" value="0" name="AllowDelete">
<label for="AllowDelete_0">否</label>
</div>
</div>
</div>
JS代码如下:
//系统默认选择是的话,不允许删除,不允许编辑
$("input:radio[name='IsSystem']").change(function(){
var val = $('input:radio[name="IsSystem"]:checked').val();
if (val == "1") {
$("input:radio[name='AllowEdit'][value='0']").attr("checked",true);
$("input:radio[name='AllowDelete'][value='0']").attr("checked", true);
}else{
$("input:radio[name='AllowEdit'][value='1']").attr("checked", true);
$("input:radio[name='AllowDelete'][value='1']").attr("checked", true);
}
});
效果图如下:
解决方法:每次Jquery赋值都需要控制同一name的其他值的属性。
修改后的JS代码如下:
//系统默认选择是的话,不允许删除,不允许编辑
$("input:radio[name='IsSystem']").change(function(){
var val = $('input:radio[name="IsSystem"]:checked').val();
if (val == "1") {
$("input:radio[name='AllowEdit'][value='1']").removeAttr("checked");
$("input:radio[name='AllowDelete'][value='1']").removeAttr("checked");
$("input:radio[name='AllowEdit'][value='0']").attr("checked",true);
$("input:radio[name='AllowDelete'][value='0']").attr("checked", true);
$("input:radio[name='AllowEdit']").attr("disabled", true);
$("input:radio[name='AllowDelete']").attr("disabled", true);
}else{
$("input:radio[name='AllowEdit']").removeAttr("disabled");
$("input:radio[name='AllowDelete']").removeAttr("disabled");
$("input:radio[name='AllowEdit'][value='0']").removeAttr("checked");
$("input:radio[name='AllowDelete'][value='0']").removeAttr("checked");
$("input:radio[name='AllowEdit'][value='1']").attr("checked", true);
$("input:radio[name='AllowDelete'][value='1']").attr("checked", true);
}
});
效果图如下:
问题已解决。
