javascript - 在 PrimeFaces 中更新某些组件时自动调用 javascript

Question

Primefaces 5

我有以下示例:

<script>

function init () { 
  $("#myspan").doSomething;
}
</script>

<h:form rendered="some condition">
  <span id="myspan" />

</h:form>

如何在每次更新表单时自动调用 init()？

Answer 1

要重新运行脚本，只需重新呈现调用它的标签即可。假设表单在“更新”时重新呈现，这将执行:

<script>

function init () { 
  $("#myspan").doSomething;
}
</script>

<h:form rendered="some condition">
  <script type="text/javascript">init()</script>
  <span id="myspan" />

</h:form>
