1.在原窗口打开链接
<input type="button" value="查询" onClick="location='pageUtil/getPage.action'">
<button onClick="location.href='pageUtil/getPage.action'" 查询</button>
<form action="pageUtil/getPage.action">
<input type="submit" value="查询">
</form>
2.在新窗口中打开链接
<input type="button" value="查询" onClick="window.open('pageUtil/getPage.action')">
<button onClick="window.open('pageUtil/getPage.action')">查询</button>
<form action="pageUtil/getPage.action" target="_blank">
<input type="submit" value="查询">
</form>
注意：onClick调用的代码里的引号在只有一重时可以单双嵌套，超过两重就必须用"\"号转义且转义的引号必须跟里层的引号一致，如：
<button onClick="this.innerHTML=’& lt;font color=\’red\’>pageUtil/getPage.action</font>’">查询< /button>
或
<button onClick=’this.innerHTML="< font color=\"red\">pageUtil/getPage.action</font>"’>查询< /button>
onclick="window.history.back()"
