Example analysis of use function usage example in SeaJS

This article describes the usage of use function in SeaJS. Share it for your reference, as follows:

With the implementation of module definition specifications such as define, we can develop many modules. But having a bunch of modules doesn't work, we have to make them run. In SeaJS, it is very easy to start the module system:

<script src="path/to/"></script>
<script>
('./main');
</script>

Used to load modules in pages. Through the use method, any module can be loaded in the page.

grammar: (id, callback?)

// Load the module main and execute the specified callback when the load is completed('./main', function(main) {
();
});

The use method can also load multiple modules at once:

// Concurrently load module a and module b, and when both loading is completed, execute the specified callback(['./a', './b'], function(a, b) {
();
();
});

The callback parameter is optional. When only one module is loaded and no callback is required, you can usedata-mainProperties to simplify:

<script src="path/to/" data-main="./main"></script>

The above code is equivalent to:

<script src="path/to/"></script>
<script>
('./main');
</script>

SeaJS also providesdata-config To load the configuration file:

<script src="path/to/" data-config="path/to/config"></script>

data-config equivalent:

({
preload: ['path/to/config']
});

Path resolution rules andConsistent.

What I use here is:

<script src="/js/lib/" data-config="/js/"></script>
<script>
('/js/main', function(main) {
main.banner_focus('#focus');
});

Note:main is the module name.Functions defined for modules can pass parameters over.
