我有一个我正在构建的计算应用程序,并且我有输入显示逗号的地方,并且尽管使用逗号仍然可以运行计算,但现在我无法使用千位分隔符显示输出逗号。我几乎尝试了所有我能想到的东西。有人能告诉我我可能会离开的地方。
这是我的剧本:
jQuery( document ).ready( function( $ ) {
// SHOW OUTPUT DIV ONLY WHEN ALL FIELDS ARE COMPLETED
$( '#calc-top' ).bind( 'keyup change', function() {
var orderAmount = $( '#orderAmt' ).val().replace( '', ',' );
if ( orderAmount !== "" && $( "#duration option:selected" ).val() !== "" && $( "#debitFreq option:selected" ).val() !== "" ) {
$( 'div#calc-bottom' ).css( 'display', 'block' );
} else {
$( 'div#calc-bottom' ).css( 'display', 'none' );
}
} );
} );
jQuery(document).ready(function($){
$("#orderAmt").keyup(function(event) {
// skip for arrow keys
if (event.which >= 37 && event.which <= 40) {
event.preventDefault();
}
var $this = $(this);
var num = $this.val().replace(/,/gi, "");
var num2 = num.split(/(?=(?:[0-9]{3})+$)/).join(",");
console.log(num2);
// the following line has been simplified. Revision history contains original.
$this.val(num2);
});
});
// end jQuery
// CALCULATE USER INPUT AND WRITE OUTPUT TO HTML ELEMENTS
function calculate() {
var orderAmt = parseFloat(document.getElementById( "orderAmt" ).value.replace(/,/g, ''));
var duration = document.getElementById( "duration" ).value || 0;
var debitFreq = document.getElementById( "debitFreq" ).value || 0;
var outputAmt = document.getElementById( 'outputAmt' ) || 0;
var numPayments = document.getElementById( 'numPayments' ) || 0;
// CALCULATE NUMBER OF PAYMENTS
if ( debitFreq == 7 ) {
numPayments = Math.floor( duration / 7 );
} else if ( debitFreq == 30 ) {
numPayments = Math.floor( duration / 30 );
}
document.getElementById( 'numPayments' ).innerHTML = numPayments;
// CALCULATE PAYMENT AMOUNT
var stepA = (orderAmt / numPayments);
var stepB = Math.floor( (((15 / 1000) * (duration / 360)) * 12) * orderAmt ) || 0;
var stepC;
if ( debitFreq == 7 ) {
stepC = 0.10;
//} else if (debitFreq == 30) {
//stepC = 0.05;
} else {
stepC = 0;
}
var stepD = 0;
//if ((duration == 30) && (debitFreq == 30)) {
//stepD = 0.05;
//} else {
//stepD = 0;
//}
var stepE = stepC - stepD;
var stepF = Math.floor( (((15 / 1000) * (duration / 360)) * 12) * orderAmt ) || 0;
var stepG = Math.ceil( stepE * stepF );
var stepH = stepB - stepG;
var stepI = stepH / numPayments;
var monthlyPayments = stepI + stepA;
outputAmt.innerHTML = monthlyPayments.toFixed( 2 ) || 0;
// OUTPUT WILL SHOW CORRECT DEBIT FORMATS BASED ON USER INPUT (i.e. 'week', 'weeks', 'month', 'months')
var outputDefault1;
if ( document.getElementById( "debitFreq" ).value == 7 ) {
outputDefault1 = "week";
} else if ( document.getElementById( "debitFreq" ).value == 30 ) {
outputDefault1 = "month";
}
document.getElementById( "outputTerm1" ).innerHTML = outputDefault1;
var outputDefault2;
if ( document.getElementById( "debitFreq" ).value == 7 ) {
outputDefault2 = "weeks";
} else if ( document.getElementById( "debitFreq" ).value == 30 ) {
outputDefault2 = "months";
}
document.getElementById( "outputTerm2" ).innerHTML = outputDefault2;
}
// end calculate function
// ONLY ALLOW NUMERIC INPUT, NO ALPHA OR SPECIAL CHARACTERS EXCEPT COMMAS
function isNumberKey( evt ) {
var theEvent = evt || window.event;
var key = theEvent.keyCode || theEvent.which;
key = String.fromCharCode( key );
var regex = /^[0-9.,]+$/;
if ( !regex.test( key ) ) {
theEvent.returnValue = false;
if ( theEvent.preventDefault ) {
theEvent.preventDefault();
}
}
}
// TRIGGER EVENTS WHEN THE USER ENTERS DATA
var userinputNum = document.getElementById( "orderAmt" );
userinputNum.oninput = calculate;
userinputNum.onkeypress = isNumberKey;
var userinputDays = document.getElementById( "duration" );
userinputDays.onchange = calculate;
var userinputFreq = document.getElementById( "debitFreq" );
userinputFreq.onchange = calculate;

非常感谢任何帮助!

试试这个:
注意:出于可读性/可理解性的目的,以下函数非常冗长。您可能希望将其简化为生产
你会改变
outputAmt.innerHTML = monthlyPayments.toFixed( 2 ) || 0
的 - &GT; 强> outputAmt.innerHTML = placeCommas(monthlyPayments);
function placeCommas(number) {
if (number !== null && number !== undefined) {
number = number.toFixed(2);
var splitNum = number.split(".");
var num = splitNum[0];
var decimals = splitNum[1];
var numArr = num.split("").reverse();
var commaArr = [];
for (var i = 0; i < numArr.length; i++) {
commaArr.push(numArr[i]);
if (i !== numArr.length - 1 && i % 3 === 2) {
commaArr.push(",");
}
}
num = commaArr.reverse().join("");
number = num + "." + decimals;
return number;
}
}
console.log(placeCommas(0));
console.log(placeCommas(10));
console.log(placeCommas(100));
console.log(placeCommas(1000));
console.log(placeCommas(10000));
console.log(placeCommas(100000));
console.log(placeCommas(1000000));
console.log(placeCommas(10000000));
console.log(placeCommas(100000000));
console.log(placeCommas(1000000000));

请看一下这个updated FIDDLE,我认为这应该做你需要的。
function FormatNumber(nStr) {
nStr += '';
x = nStr.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';
var pattern = /(\d+)(\d{3})/;
while (pattern.test(x1)) {
x1 = x1.replace(pattern, '$1' + ',' + '$2');
}
return x1 + x2;
}

阻止使用箭头键,甚至任何键都不是那么用户友好。您的限制也消除了使用shift-arrow选择文本的可能性,以使用退格键删除输入。当他们用鼠标移动光标位置时,一旦键入,光标就会翻转到最后。这是异常行为,会让用户感到沮丧。
让他们输入他们想要的东西,并在他们退出输入框时进行清理。这更加用户友好。
因此我建议仅在焦点离开输入字段时应用数字格式,并在焦点再次进入时立即删除所有格式。
这里还有一个正则表达式replace
,可以一次性应用格式:
$(this).val()
.replace(/[^\d.]/gi, "") // clean-up
.replace(/\B(\d{3})(?=(?:\d{3})*(?:\.|$))/g, ',$1'); // format
