require.js+knockout.js+.underscore模板引擎的使用

本文主要是介绍require.js+knockout.js+.underscore模板引擎的使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

第一种使用方式：

HTML：

<ul data-bind="template: { name: 'peopleList' }"></ul><script type="text/html" id="peopleList"><% _.each(people(), function(person) { %><li><b data-bind="text: person.name"></b> is <%= person.age %> years old</li><% }) %>
</script>

JS：

/* ---- Begin integration of Underscore template engine with Knockout. Could go in a separate file of course. ---- */ko.underscoreTemplateEngine = function () { }ko.underscoreTemplateEngine.prototype = ko.utils.extend(new ko.templateEngine(), {renderTemplateSource: function (templateSource, bindingContext, options) {// Precompile and cache the templates for efficiencyvar precompiled = templateSource['data']('precompiled');if (!precompiled) {precompiled = _.template("<% with($data) { %> " + templateSource.text() + " <% } %>");templateSource['data']('precompiled', precompiled);}// Run the template and parse its output into an array of DOM elementsvar renderedMarkup = precompiled(bindingContext).replace(/\s+/g, " ");return ko.utils.parseHtmlFragment(renderedMarkup);},createJavaScriptEvaluatorBlock: function(script) {return "<%= " + script + " %>";}});ko.setTemplateEngine(new ko.underscoreTemplateEngine());
/* ---- End integration of Underscore template engine with Knockout ---- */var viewModel = {people: ko.observableArray([{ name: 'Rod', age: 123 },{ name: 'Jane', age: 125 },])        
};ko.applyBindings(viewModel);

代码演示

第二种使用方式：

HTML代码段：

<div class="l_box_temp" id="side-userInfo"></div>

JS代码段:

define(['knockout','jquery','underscore','model''text!home/view/side-userInfo.html'], function(ko, $, _, model, viewBaozhang, template) {var ViewModel = function() {var self = this;self.viewUserInfo = $('#side-userInfo');self.template = _.template(template);self.html = '';self.grade = '';self.initialize =  function() {model.getData(function(res){self.html = self.template(res);self.viewUserInfo.html(self.html);self.grade = res.grade;setTimeout(function(){ko.applyBindings(self, $('body')[0]);},0)});}}
});
