我们试图让一个投递箱改变另一个。我们有这段代码在 Firefox、safari 和 chrome 上运行良好。但在 IE 8+ 中，更改第一个下拉菜单对第二个下拉菜单没有影响。我们必须改变什么才能让它在 IE 中工作？谢谢，

我们有这个jquery：

    //set up the global variable maxChecks which stops donor ticking too many boxes
    var maxChecks
    var checkCount=0
    var boxeschecked = 0
    //now change the drop down
    jQuery.noConflict();
    jQuery(document).ready(function($) {
        $(function() {      
            $("#json-one").change(function() {
                if ($(this).val() >= "1" ) {
                    $("#hide1").slideDown("fast"); //Slide Down Effect
                }
                var $dropdown = $(this);
                var key = $dropdown.val();
                var vals = [];
                switch(key) {
            case '1': document.getElementById("t3").innerHTML ="<option value=2>&pound;2.50 per month</option>, <option value=3>&pound;30 per year</option>, <option value=1>A single donation of &pound;30</option>"; maxChecks=1; boxeschecked=0; checkCount=0; document.getElementById("nsdiv").innerHTML =""; for (var i = 0; i < 1 ; i++) {document.getElementById("nsdiv").innerHTML +='<input type="hidden" name="childid[]" value="newchild" checked>';} break;
            case '2': document.getElementById("t3").innerHTML ="<option  value=5>&pound;5 per month</option>, <option value=4>&pound;60 per year</option>, <option value=22>A single donation of &pound;60</option>"; maxChecks=2; boxeschecked=0; checkCount=0; document.getElementById("nsdiv").innerHTML =""; for (var i = 0; i < 2 ; i++) {document.getElementById("nsdiv").innerHTML +='<input type="hidden" name="childid[]" value="newchild" checked>';} break;

case 'base': vals = ['-'];
                }
                $jsontwo.empty();
            });
        });
    });

这是html：

    <select id="json-one" name="json-one">
        <option selected value="base">Please select</option>
        <option value="1">1 child</option>
        <option value="2">2 children</option>
    </select>
    <!-- this select box will be hidden at first -->
    <div style="display:none;" id="hide1">
        By donating <select id="t3" name="t3"><option>-</option></select>
    </div>

以下似乎在 IE 中工作：

    //set up the global variable maxChecks which stops donor ticking too many boxes
    var maxChecks;
    var checkCount=0;
    var boxeschecked = 0;
    //now change the drop down
    jQuery.noConflict();
    jQuery(document).ready(function($) {
        $(function() {      
            $("#json-one").change(function() {
                if ($(this).val() >= "1" ) {
                    $("#hide1").slideDown("fast"); //Slide Down Effect
                }
                var key = $(this).val();
                var vals = [];
            switch(key) {
              case "1": 
                $("#t3").html('<option value=2>&pound;2.50 per month</option> <option value=3>&pound;30 per year</option> <option value=1>A single donation of &pound;30</option>');
                maxChecks=1; 
                boxeschecked=0; 
                checkCount=0; 
                $("#nsdiv").html('');
                for (var i = 0; i < 1 ; i++) {
                    $("#nsdiv").append('<input type="hidden" name="childid[]" value="newchild" checked>');
                } 
                break;
              case "2": 
                $("#t3").html('<option  value=5>&pound;5 per month</option> <option value=4>&pound;60 per year</option> <option value=22>A single donation of &pound;60</option>'); 
                maxChecks=2; 
                boxeschecked=0; 
                checkCount=0; 
                $("#nsdiv").html('');
                for (var i = 0; i < 2 ; i++) {
                    $("#nsdiv").append('<input type="hidden" name="childid[]" value="newchild" checked>');
                } 
                break;

              case 'base': 
                vals = ['-'];
                break;
            }
            });
        });
    });
