我正在使用该指令以适当的格式显示来自此网址http://jsfiddle.net/ExpertSystem/xKrYp/
的资金有谁知道如何从输出值中删除$符号并仅转换实际金额?
尝试了一些不同的东西,但我无法完成我想要的东西。
这也是指令:
app.directive('realTimeCurrency', function ($filter, $locale) {
var decimalSep = $locale.NUMBER_FORMATS.DECIMAL_SEP;
var toNumberRegex = new RegExp('[^0-9\\' + decimalSep + ']', 'g');
var trailingZerosRegex = new RegExp('\\' + decimalSep + '0+$');
var filterFunc = function (value) {
return $filter('currency')(value);
};
function getCaretPosition(input){
if (!input) return 0;
if (input.selectionStart !== undefined) {
return input.selectionStart;
} else if (document.selection) {
// Curse you IE
input.focus();
var selection = document.selection.createRange();
selection.moveStart('character', input.value ? -input.value.length : 0);
return selection.text.length;
}
return 0;
}
function setCaretPosition(input, pos){
if (!input) return 0;
if (input.offsetWidth === 0 || input.offsetHeight === 0) {
return; // Input's hidden
}
if (input.setSelectionRange) {
input.focus();
input.setSelectionRange(pos, pos);
}
else if (input.createTextRange) {
// Curse you IE
var range = input.createTextRange();
range.collapse(true);
range.moveEnd('character', pos);
range.moveStart('character', pos);
range.select();
}
}
function toNumber(currencyStr) {
return parseFloat(currencyStr.replace(toNumberRegex, ''), 10);
}
return {
restrict: 'A',
require: 'ngModel',
link: function postLink(scope, elem, attrs, modelCtrl) {
modelCtrl.$formatters.push(filterFunc);
modelCtrl.$parsers.push(function (newViewValue) {
var oldModelValue = modelCtrl.$modelValue;
var newModelValue = toNumber(newViewValue);
modelCtrl.$viewValue = filterFunc(newModelValue);
var pos = getCaretPosition(elem[0]);
elem.val(modelCtrl.$viewValue);
var newPos = pos + modelCtrl.$viewValue.length -
newViewValue.length;
if ((oldModelValue === undefined) || isNaN(oldModelValue)) {
newPos -= 3;
}
setCaretPosition(elem[0], newPos);
return newModelValue;
});
}
};
});

尝试https://github.com/bcherny/format-as-currency:)
或者如果您想使用自己的版本,请将空字符串作为第二个参数传递给currency
过滤器。见https://docs.angularjs.org/api/ng/filter/currency
