如何在Knockout中设置模板绑定URL前缀？

ko.bindingHandlers.templateWithPrefix = {
  init: function(element, valueAccessor, allBindings, viewModel, bindingContext) {
    var options = ko.unwrap(valueAccessor());
    var prefix = "http://example.com/templates/"; // 设置URL前缀
    options.name = prefix + options.name; // 添加前缀到模板绑定的URL
    ko.bindingHandlers.template.init(element, function() { return options; }, allBindings, viewModel, bindingContext);
  },
  update: function(element, valueAccessor, allBindings, viewModel, bindingContext) {
    var options = ko.unwrap(valueAccessor());
    var prefix = "http://example.com/templates/"; // 设置URL前缀
    options.name = prefix + options.name; // 添加前缀到模板绑定的URL
    ko.bindingHandlers.template.update(element, function() { return options; }, allBindings, viewModel, bindingContext);
  }
};

<div data-bind="templateWithPrefix: { name: 'myTemplate.html' }"></div>
