function delete_onclick(idValue){

document.all.creditRankInfoId.value = idValue;

document.forms(\\\"creditItemsForm\\\").actions.value= \\\"deleteCreditRankInfo\\\";

document.forms(\\\"creditItemsForm\\\").submit();

alert(111);
}
已经弹出111了，但是没进入我的deleteCreditRankInfo方法，struts的配置文件里面检查了下，方法名没错。看了下tomcat的日志，得到如下的异常报告

<pre class=\\\"answer-content\\\">document.forms(\\\"creditItemsForm\\\").actions.value= \\\"deleteCreditRankInfo\\\";

document.forms(\\\"creditItemsForm\\\").submit();
改为：

document.creditItemsForm.action.value= \\\"deleteCreditRankInfo\\\";

document.creditItemsForm.submit();

<pre class=\\\"answer-content\\\">document.creditItemsForm.action= \\\"deleteCreditRankInfo\\\";
document.creditItemsForm.submit();
js的调式是比较麻烦的。。。
