在JavaScript点击处理程序之间传递变量

如何在javaScript点击处理程序中传递变量

我已经分配了var条件选择=$this.val；in.changefunction。如何在第二个单击句柄中获取此变量的值，即启用$process signs报废按钮。单击函数{

如何在这两个函数之间传递变量

$('input:checkbox').change(function() {
        /*get the parent node of the radio and then hide only its siblings*/
        $(this).parent('label').siblings().toggle();
        if ($('.sign-condition').is(':checked')) {
            var condition_selction = ($(this).val());
        }
        if ($('.sign-reason').is(':checked')) {
            var reason_selction = ($(this).val());
        }
        //Check that both select fields have a value
        if (condition_selction != null && reason_selction != null) {
            $("#process-signs-scrap-scrapped-button-disabled").hide();
            $("#process-signs-scrap-scrapped-button-enabled").show();
        } else {
            $("#process-signs-scrap-scrapped-button-disabled").show();
            $("#process-signs-scrap-scrapped-button-enabled").hide();
        }
    });

    $( "#process-signs-scrap-scrapped-button-enabled" ).click(function() {



            var process_signs_scrap_condition = condition_selction;


            var process_signs_scrap_reason = reason_selction


            // Open the timer modal
            $('#process-signs-scrap-scrapped-modal').modal('show');

全局声明这两个var，以便可以在这两个函数中访问它们

var condition_selction; // like this
var reason_selction;

$('input:checkbox').change(function() {
    /*get the parent node of the radio and then hide only its siblings*/
    $(this).parent('label').siblings().toggle();
    if ($('.sign-condition').is(':checked')) {
        condition_selction = ($(this).val()); // removed declaration 
    }
    if ($('.sign-reason').is(':checked')) {
        reason_selction = ($(this).val());
    }
    //Check that both select fields have a value
    if (condition_selction != null && reason_selction != null) {
        $("#process-signs-scrap-scrapped-button-disabled").hide();
        $("#process-signs-scrap-scrapped-button-enabled").show();
    } else {
        $("#process-signs-scrap-scrapped-button-disabled").show();
        $("#process-signs-scrap-scrapped-button-enabled").hide();
    }
});

$( "#process-signs-scrap-scrapped-button-enabled" ).click(function() {



        var process_signs_scrap_condition = condition_selction;


        var process_signs_scrap_reason = reason_selction


        // Open the timer modal
        $('#process-signs-scrap-scrapped-modal').modal('show');

您可以将值传递给按钮上的数据属性，然后在单击按钮时访问数据属性及其good to go

$'input:checkbox'.changefunction{ 如果“$”。符号条件“.”为“：已选中”{ var condition_selection=$this.val； $process signs报废按钮已启用。属性“数据值”，条件选择； } } $process signs报废按钮已启用。单击功能{ var condition_Selection=$this.attr'data-value'； console.log复选框的值为+条件选择； } 先点击我

单击“我最后一个”这两个函数的全局变量或变量范围是否相同？
