How do you include a raw, uncompiled partial in dust.js?

阅读更多关于 How do you include a raw, uncompiled partial in dust.js?

问题 I have dust working reasonably well, but I'd like to be able to include a file, such as a css file, without compiling and rendering it. It seems like maybe I need to create an onLoad handler that loads the file and registers the content directly. Is there a way to do this within dust already? 回答1: You can take advantage of Dust's native support for streams and promises to make file inclusion really nice. The exact implementation depends on whether you're running Dust on the server or the

阅读更多关于 Dust if condition

问题 I'm having trouble with a dust if condition. I have a partial that points to 2 different dust templates depending on the Country code {>"receipt/merchantInfo/merchantInfo_{countryCode}"/} I'm trying to make an if else condition that will figure out if the {countryCode} is US. Example: {@if cond="'{countryCode}' == 'US'"} <p>is country code US</p> {:else} <p>is NOT country code US</p> {/if} This isn't working. Anyone have an idea where I went wrong with this? 回答1: The @if helper has been

$idx and $len in a dust.js conditional statement

阅读更多关于 $idx and $len in a dust.js conditional statement

问题 The documentation on dust is just awful , I've already perused everything I can possibly find and cannot figure out how this is supposed to work. I'm having this problem with the supposed special values $idx and $len, which, if I have guessed correctly, return the current index while iterating over an array-like section and the length of said array-like section. I have an @if condition (multiple actually) that I'm trying to workout to format a template, and the values are just not working as

问题 I want to use Dust.js as a client template engine. I have a data json like this: var data = { "Foo": [{ "somekey": "somevalue", "otherkey": "othervalue" }, { "somekey": "somevalue", "otherkey": "othervalue" }], "Bar": [{ "somekey": "somevalue", "otherkey": "othervalue" }, { "somekey": "somevalue", "otherkey": "othervalue" }] } I do not know in advance what uppermost object keys will be - I do not know Foo and Bar keys, they can be any value. So, I need to iterate through this json by keywords

Using dustjs how do I show a block of code when an array's size is greater than one

阅读更多关于 Using dustjs how do I show a block of code when an array's size is greater than one

问题 I am using dust 1.1.1. I've tried nesting the @size help inside of an @if but that broke. Another trick to it is once I've determined the length is greater than one I then want to iterate through the array. 回答1: The Dust grammar does not allow a helper to be used inside another helper, except in the body. Instead, I would try something like this: {#myArray} {@gt key=$len value=1}{.}{/gt} {/myArray} This will only output the value of the element in the array if the length of the array ( $len )

Is it possible / sensible to use external templating engine like dust.js or any other with anjularjs?

阅读更多关于 Is it possible / sensible to use external templating engine like dust.js or any other with anjularjs?

问题 I had this urge to use dust.js templates as it provides a much better performance for UI rendering by caching the templates. But in my current project we are using angularjs. It is even possible/sensible to use dust.js or any other templating engine with angular js ?? Even if i use dust.js will I lose the 2-way binding .. ? Please suggest considering a relatively large SPA.. ? P.S. I am a novice in both angular and dust. 回答1: Sounds like a good use case for a filter! Be aware that dust.js is
