What does google.setOnLoadCallback(initialize) function exactly mean?
提问by Abhilash Muthuraj
While coding JavaScript and Ajax, there is no proper documentation for this function. I searched this term using api src="http://www.google.com/jsapi"and searchControl.execute("abhilashm86");.
在编写 JavaScript 和 Ajax 时，没有针对此功能的适当文档。我使用api src="http://www.google.com/jsapi"and搜索了这个词searchControl.execute("abhilashm86");。
How is this google.setOnLoadCallback(initialize)called internally? Is this function just for a new search term when the user clears previous search and starts a new one?
How exactly does google.setOnLoadCallback(initialize)get trigerred?
这在google.setOnLoadCallback(initialize)内部如何调用？当用户清除以前的搜索并开始新的搜索时，此功能是否仅适用于新的搜索词？究竟是如何google.setOnLoadCallback(initialize)触发的？
回答by Matthew Flaschen
Your initialize function will be called when your document (including the Google API) is fully loaded. So you should wrap any code that uses the API in the function you pass in:
当您的文档（包括 Google API）完全加载时，您的 initialize 函数将被调用。因此，您应该将任何使用 API 的代码包装在您传入的函数中：
E.g.
例如
google.setOnLoadCallback(function()
{
var searcher = new google.search.SearchControl();
// More code that depends on the API.
});

The documentationsays:
文档说：
Use google.setOnLoadCallback to register the specified handler function to be called once the document loads instead of GSearch.setOnLoadCallback.
使用 google.setOnLoadCallback 注册指定的处理程序函数以在文档加载后调用，而不是 GSearch.setOnLoadCallback。
