addClass - 无法识别新类

Question

我有一个文本框。我根据单选按钮用于两个不同的条目。当选择单选按钮时，我更改name属性并删除旧类并添加新类（keyup-numeric或keyup-charNumOnly）。根据课程的不同，执行编辑功能。使用Chrome DEV工具，我看到课程正在按预期更改（回到第四个没问题）。但是keyup-numeric函数是唯一被执行的函数。我是JQUERY的新手。所以这可能是不经意的。 感谢帮助。

$(document).ready(function() {
 	$("#radio1").click(function() {
		$('p.error-keyup-1').remove();
		$("#requestedInput").val("Update Address using Account Number").attr('name','acctNumber').attr('maxlength','10');
		$("#requestedInput").removeClass().addClass('inputNumTextBox keyup-numeric');
	});		
 	$("#radio2").click(function() {		
		$('p.error-keyup-1').remove();
 		$("#requestedInput").val("Update Account Number using Address").attr('name', 'Address').attr('maxlength','23');
		$("#requestedInput").removeClass().addClass('inputNumTextBox keyup-charNumOnly');
	} );
		
 	$('.keyup-numeric').keyup(function() {
		$('p.error-keyup-1').remove();
		var inputVal = $(this).val();
		var numericReg = /^\d*[0-9](|.\d*[0-9]|,\d*[0-9])?$/;
		var AcctReg9 = /^9/;
		if(!numericReg.test(inputVal)) {	
			$('<p class="error-keyup-1 errorStyle centerText">Numeric characters only</p>').appendTo('#enterRequestDataSection');
		}
		if(!AcctReg9.test(inputVal)) {	
			$('<p class="error-keyup-1 errorStyle centerText">Accounts Start with 9 .... Required</p>').appendTo('#enterRequestDataSection');
		}
		if ($('#requestedInput').val().length==0) {
				$('p.error-keyup-1').remove();			
			}
		});	
	
	$('.keyup-charNumOnly').keyup(function() {
		alert('keyup-charNumOnly I'); 
		$('p.error-keyup-1').remove();
		var inputVal = $(this).val();	
		var characterReg = /^\s*[a-zA-Z0-9,\s]+\s*$/;
		if(!characterReg.test(inputVal)) {	
			alert('keyup-charNumOnly II'); 
			$('<p class="error-keyup-1 errorStyle centerText">cRAP</p>').appendTo('#enterRequestDataSection');
		}
		if ($('#requestedInput').val().length==0) {
				$('p.error-keyup-1').remove();			
			}
		});

Answer 1

当keyup事件在文档之后绑定时，keyUpCharNumOnly类不存在（ready（。

您将要使用：

$('.keyup-charNumOnly').on('keyup', function() {

Answer 2

试试这个：

$(document).ready(function() {
    $("#radio1").click(function() {
        $('p.error-keyup-1').remove();
        $("#requestedInput").val("Update Address using Account Number").attr('name','acctNumber').attr('maxlength','10');
        $("#requestedInput").removeClass().addClass('inputNumTextBox keyup-numeric');
    });     
    $("#radio2").click(function() {     
        $('p.error-keyup-1').remove();
        $("#requestedInput").val("Update Account Number using Address").attr('name', 'Address').attr('maxlength','23');
        $("#requestedInput").removeClass().addClass('inputNumTextBox keyup-charNumOnly');
    } );

$(document).on('keyup', "#requestedInput.keyup-numeric", function() {
        $('p.error-keyup-1').remove();
        var inputVal = $(this).val();
        var numericReg = /^\d*[0-9](|.\d*[0-9]|,\d*[0-9])?$/;
        var AcctReg9 = /^9/;
        if(!numericReg.test(inputVal)) {    
            $('<p class="error-keyup-1 errorStyle centerText">Numeric characters only</p>').appendTo('#enterRequestDataSection');
        }
        if(!AcctReg9.test(inputVal)) {  
            $('<p class="error-keyup-1 errorStyle centerText">Accounts Start with 9 .... Required</p>').appendTo('#enterRequestDataSection');
        }
        if ($('#requestedInput').val().length==0) {
                $('p.error-keyup-1').remove();          
            }
        }); 


$(document).on('keyup', "#requestedInput.keyup-charNumOnly", function() {
        alert('keyup-charNumOnly I'); 
        $('p.error-keyup-1').remove();
        var inputVal = $(this).val();   
        var characterReg = /^\s*[a-zA-Z0-9,\s]+\s*$/;
        if(!characterReg.test(inputVal)) {  
            alert('keyup-charNumOnly II'); 
            $('<p class="error-keyup-1 errorStyle centerText">cRAP</p>').appendTo('#enterRequestDataSection');
        }
        if ($('#requestedInput').val().length==0) {
                $('p.error-keyup-1').remove();          
            }
        });

});    // End of JQUERY CODE
