第44行中的if ... else不起作用。我检查了jQuery post返回的值，它返回'Y'或'N'。我正在测试这个条件并根据返回的值执行一些任务。但是那部分不起作用，内部的警报既不工作也没有其他的show事件正在工作。无法找到错误。

答案 0 :(得分：1)
为每个人的理智添加一些格式。另外，看看我放置console.log的位置，它应该可以帮助你弄清楚if语句中的确切内容。
jQuery.noConflict();
jQuery(document).ready(function() {
jQuery('#tldno').focus();
jQuery( "#datepicker" ).datepicker({
yearRange: '-60:-18',
changeMonth: true,
changeYear: true,
dateFormat: "dd-mm-yy",
altFormat:"yy-mm-dd",
altField:"#stddate"
});
jQuery('#submit').hide();
});
jQuery("#tldno").change(function(){
var rep_sel=jQuery("[name='unit']:checked").val();
var name = rep_sel.concat(jQuery("#tldno").val());
jQuery.post('tld_search_hpu.php', {name: name}, function(data) {
console.log(data);
if (data === 'Y') {
alert("Data Exists");
} else {
jQuery('#submit').show();
}
});
});
