Question

我在javascript中创建了此功能，以便在点击ahref链接时

$(document).ready(function() {
    $("#ProcessCharges").click(function() {
        alert("testing");
        if($("#customerbilling_unitprice").val() == "") {
            alert("Please Enter a Unit Price");
            return false;
        }
        if($("#customerbilling_resellercost").val() == "") {
            alert("Please Enter a Reseller Unit Price");
            return false;
        }
        if($("#customerbilling_todate").val() == "") {
            alert("Please Enter a To Date");
            return false;
        }
        if($("#customerbilling_fromdate").val() == "") {
            alert("Please Enter a From Date");
            return false;
        }

        //work out number of days between the two dates
        var tDate = new Date($("#customerbilling_todate").val());
        var fDate = new Date($("#customerbilling_fromdate").val());
        var diff=tDate-fDate;
        var days_between= diff / 1000 / 60 / 60 / 24;

        //do the cost per month times 12 (months)
        var year_cost = $("#customerbilling_unitprice").val() * 12;
        // RESELLER //
        var year_cost_reseller = $("#customerbilling_resellercost").val() * 12;
        // RESELLER //

        //do the yearly cost / 365
        //this will give the daily cost
        var daily_cost = year_cost / 365;
        // RESELLER //
        var daily_cost_reseller = year_cost_reseller / 365;
        // RESELLER //

        //check number of days
        alert(days_between);
        if(days_between == '29' or days_between == '30' or days_between == '31' or days_between == '0') {
            //its a FULL month
            var total_cost = parseFloat( $("#customerbilling_unitprice").val().toFixed(2) );
            // RESELLER //
            var total_cost_reseller = parseFloat( $("#customerbilling_resellercost").val().toFixed(2) );
            // RESELLER //
        } else {
            //now do the daily cost times cost_per_month
            var total_cost = daily_cost * days_between;
            var total_cost = parseFloat( total_cost.toFixed(2) );
            // RESELLER //
            var total_cost_reseller = daily_cost_reseller * days_between;
            var total_cost_reseller = parseFloat( total_cost_reseller.toFixed(2) );
            // RESELLER //
        }

        $("#customerbilling_unitprice").val(total_cost);
        $("#customerbilling_resellercost").val(total_cost_reseller);
    });
});

但是当点击链接时，该功能没有运行。它应该做的第一件事是显示它没有做的警告框

我在这里创建了一个小提琴来显示完整的代码：http://jsfiddle.net/0v02nLnc/

Answer 1

您使用的语法不正确。替换你的病情

if(days_between == '29' or days_between == '30' or days_between == '31' or days_between == '0') {

到

  if(days_between == '29' || days_between == '30' || days_between == '31' || days_between == '0') {

Answer 2

if(days_between == '29' or days_between == '30' or days_between == '31' or days_between == '0') {

应更改为

if(days_between == '29' || days_between == '30' || days_between == '31' || days_between == '0') {

javascript .click（function（）没有运行
