JavaScript表单提交-确认或取消提交对话框对于具有询问字段是否正确填写的警报的简单表单,我需要一个这样做的函数:使用两个选项单击按钮时显示一个警告框:如果单击“确定”,则提交表单。如果单击“取消”,则“警报”框将关闭,并可对窗体进行调整和重新提交。我认为JavaScript确认会起作用,但我似乎不知道怎么做。我现在的代码是:function show_alert() { alert("xxxxxx");}<form> <input type="image" src="xxx" border="0" name="submit" onclick="show_alert();" alt="PayPal - The safer, easier way to pay online!" value="Submit"></form>
