Question

我很难过，所以现在我转向我的同事们寻求帮助。这可能是我忽略的非常简单的事情，但你知道当你对某些事情看起来过于苛刻时会是怎样的，通常情况就是这样，你就会错过它。任何方式漫无目的地漫无目的！到了这一点！

我有这个应用程序，我只需要帮助它的片段。它已经与bootstrap 3放在一起，所以我不知道这是否与它有关。我想要做的是，点击复选框#mailing_address，检查更改，如果选中，则添加当前地址部分的值#p_address，＃p_address2，＃p_city，＃p_state，＃p_zip ，在下一组输入中各自的#m_值，然后禁用#m_输入，以便它们不能被更改。这部分工作

如果未选中该框，则再次更改#mailing_address，清除所有#m_输入并再次启用输入。这是不起作用的部分。

以下是给我这个问题的表单摘录

用于引用包含文件＆quot; state_list_options.php＆＃39;的include语句只是一个包含状态名称和缩写的选项列表，如下所示：

<option value='AZ'>Arizona</option>

这是我为其命名的Jquery代码

$(document).ready(function(){
    //check if the mailing address checkbox is checked
    //if so then we will fill the mailing address in with the information from current address   then hide all the mailing address fields
    //else clear the mailing address fields and show them again
    //set variables 
    var p_values = ['p_address', 'p_address2', 'p_city', 'p_state', 'p_zip'];
    var m_values = ['m_address', 'm_address2', 'm_city', 'm_state', 'm_zip'];
    $("#mailing_address").change(function(){
        if($(this.checked)){
        //if checked get the values from the current address fields
            for(var i = 0; i < p_values.length; i++){
                $('#'+m_values[i]+'').val($('#'+p_values[i]+'').val());
                $('#'+m_values[i]+'').attr('disabled', 'disabled');
            }
        }
        else{
            //this is the part that is failing
            for(var i = 0; i < p_values.length; i++){
                $('#'+m_values[i]+'').val("");
                $('#'+m_values[i]+'').removeAttr('disabled');
            }
        }
    });
});

是否与我使用id而不是输入的类或名称这一事实有关？我认为这不重要。我真的不知道，我绝对难过。如果需要，我可以添加更多细节让我知道！

Answer 1

从$() jsFiddle

周围移除this.checked

if(this.checked){

如果你想让它成为一个jQuery对象，那么它就像这样

if($(this).is(':checked')){

Answer 2

使用if($(this).is(':checked')){ - 检查jQuery的正确语法。
