Bootstrap

Besides its default meaning, <script> tag supports two more configuration with its type property in the top level component of a page.

• type="data": For initial data configuration, the data defined here will overwrite the data definition in the <script>.
• type="config": For configuration definition.

<script type="data">
  /* (optional) the definition of initial data */
</script>

<script type="config">
  /* (optional) the definition of configuration */
</script>

Initial data definition

Sometimes, it is hard to maintain huge data structure in the default <script> tag. So Weex allows us to have a <script type="data"> tag to define initial data. The data defined in here will totally replace the data defined in the default <script> tag.

here is an example:

<script type="data">
{
  title: 'Alibaba',
  date: new Date().toLocaleString()
}
</script>

script configuration

Weex also allows us to do some configuration with a <script type="config">, So far, we only support the downgrade configs.

• downgrade.osVersion
• downgrade.appVersion
• downgrade.weexVersion
• downgrade.deviceModel
