javascript - 在显示输出之前先比较所有 If 语句

问题描述

我以为我已经弄清楚了逻辑；但是，我得到的输出是第一个被发现为真的 IF 语句。为了在显示警告框之前先通过逻辑并找到正确的输出，我是否需要使用 switch 语句？

如果是这样，这看起来像什么？我一直在尽职调查，似乎无法弄清楚 switch 语句如何适用于我的情况。

    function get_recommendation() {
  var ES = "Everyday Solutions";
  var IL = "ILAB";
  var SP = "Spark";
  var IT = "IT Innovation";

  $(document).ready(function() {
    //If Opco is checked, and both ES are checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#Yes1').is(':checked')) && ($('#Yes2').is(':checked'))) {
	var case1 = alert("Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL + " or " + SP);
    }
    //If Opco is checked, both ES are checked yes, and ILAB is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#Yes1').is(':checked')) && ($('#Yes2').is(':checked')) && ($('#Yes3').is(':checked'))) {
	var case2 = alert("Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL);
    }
    //If Opco is checked, both ES are checked yes, ILAB is checked no, and Spark is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#Yes1').is(':checked')) && ($('#Yes2').is(':checked')) && ($('#No3').is(':checked')) && ($('#Yes4').is(':checked'))) {
	var case3 = alert("Primary Recommendation: " + ES + "\n Secondary Recommendation: " + SP);
    }
    //If Opco is checked, both ES are checked yes, ILAB is checked yes, and Spark is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#Yes1').is(':checked')) && ($('#Yes2').is(':checked')) && ($('#Yes3').is(':checked')) && ($('#Yes4').is(':checked'))) {
	var case4 = alert("Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL + " or " + SP);
    }
    //If Opco is checked, both ES are checked no, and ILAB is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#No1').is(':checked')) && ($('#No2').is(':checked')) && ($('#Yes3').is(':checked'))){
	var case5 = alert("Primary Recommendation: " + IL + "\n Secondary Recommendation: " + SP);
    }
    //If Opco is checked, both ES are checked no, ILAB is checked yes, and Spark is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#No1').is(':checked')) && ($('#No2').is(':checked')) && ($('#Yes3').is(':checked')) && ($('#Yes4').is(':checked'))){
	var case6 = alert("Primary Recommendation: " + IL + " or " + SP);
    }
    //If Opco is checked, both ES are checked no, Spark is checked yes
    if (($('input[name="opco"]:checked').length > 0) && ($('#No1').is(':checked')) && ($('#No2').is(':checked')) && ($('#Yes4').is(':checked'))){
	var case7 = alert("Primary Recommendation: " + SP);
    }
    //If IT is checked yes
    if ($('#Yes5').is(':checked')) {
        var case8 = alert("Primary Recommendation: " + IT);
    }

  });

解决方案

您应该设置一个变量，而不是许多不同的变量。alert()并且在设置变量时不要调用。

var message;

if ($('input[name="opco"]:checked').length > 0) {
    if ($('#Yes1').is(':checked') && $('#Yes2').is(':checked')) {
        message = "Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL + " or " + SP;
    }
    //If Opco is checked, both ES are checked yes, and ILAB is checked yes
    if ($('#Yes1').is(':checked') && $('#Yes2').is(':checked') && $('#Yes3').is(':checked')) {
        message = "Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL;
    }
    //If Opco is checked, both ES are checked yes, ILAB is checked no, and Spark is checked yes
    if ($('#Yes1').is(':checked') && $('#Yes2').is(':checked') && $('#No3').is(':checked') && $('#Yes4').is(':checked')) {
        message = "Primary Recommendation: " + ES + "\n Secondary Recommendation: " + SP;
    }
    //If Opco is checked, both ES are checked yes, ILAB is checked yes, and Spark is checked yes
    if ($('#Yes1').is(':checked') && $('#Yes2').is(':checked') && $('#Yes3').is(':checked') && $('#Yes4').is(':checked')) {
        message = "Primary Recommendation: " + ES + "\n Secondary Recommendation: " + IL + " or " + SP;
    }
    //If Opco is checked, both ES are checked no, and ILAB is checked yes
    if ($('#No1').is(':checked') && $('#No2').is(':checked') && $('#Yes3').is(':checked')) {
        message "Primary Recommendation: " + IL + "\n Secondary Recommendation: " + SP;
    }
    //If Opco is checked, both ES are checked no, ILAB is checked yes, and Spark is checked yes
    if ($('#No1').is(':checked') && $('#No2').is(':checked') && $('#Yes3').is(':checked') && $('#Yes4').is(':checked')) {
        message = "Primary Recommendation: " + IL + " or " + SP;
    }
    //If Opco is checked, both ES are checked no, Spark is checked yes
    if ($('#No1').is(':checked') && $('#No2').is(':checked') && $('#Yes4').is(':checked')) {
        message = "Primary Recommendation: " + SP;
    }
}
//If IT is checked yes
if ($('#Yes5').is(':checked')) {
    message = "Primary Recommendation: " + IT;
}

if (message) {
    alert(message);
}
