The first step is to build the query
1. Custom query statement: ${f} is the start page, ${p} is the number of pages, and the initial value is as shown in the figure
select * from table limit ${f},${p}
Set the initial value of p, or you can hard-code the parameters in the above figure, set the initial page as the page, and the default is 1 (the value of page).
Step 2: Custom button 7 buttons:
Set the template web properties for filling in or paging preview, and set it as the template customization:
Then design the loading end event
var toolbar = contentPane.toolbar;
var items = toolbar.options.items;
var customButton=items[2];//JQUERY取我们的工具栏上的按钮.items[2]代表的是第三个,也就是那个显示成文本框按钮。
//修正这个按钮的属性,让它变成文本类型,居中,鼠标放上次图标是编辑状态。
var cellValue = contentPane.curLGP.getCellValue("D1");//获取D1单元格的值就是page,也就是当前页。
customButton.setText(cellValue);
var total=contentPane.curLGP.getCellValue("C1");
if (total>parseInt(total)){
total=parseInt(total)+1;
}
contentPane.toolbar.options.items[4].setText(total);
//把总页数显示在第5个控件上,因为这个数值可能是小数,所以判断下要不要加一处理。
contentPane.toolbar.options.items[3].setText(contentPane.curLGP.getCellValue("E1"));
These values come from the first row of the cell: the value of the cell of A1, B1, C1, D1, D1, where C1 is the total number of rows queried
=$page-1 =$page+1 ds2.G(zs) =$page ="/"
Define the js of the first button home page
window.location.href="${servletURL}?viewlet=报表.cpt&op=write&page=1";//链接到fenye.cpt,page 参数=1,代表第一页。
second button previous page
var page= $("tr[tridx=0]","div.content-container").children().eq(0).html(); //取第一行第一个单元格内容。
if(page==0)
{
this.setEnable(false);
alert("页面超出指定的范围");
}
else
window.location.href="${servletURL}?viewlet=报表.cpt&op=write&page="+page//如果没有小于1就正常跳转,否则显示页面超过指定的范围,这个控件设置不可以使用。
third button current page
var toolbar = contentPane.toolbar;
var items = toolbar.options.items;
var customButton=items[2];
var inner = customButton.$table;
var btnWrapper = $("em", inner);
var $input = $("input", btnWrapper);
//取这个控件
$input.blur(function(){
var toolbar = contentPane.toolbar;
var items = toolbar.options.items;
var customButton=items[2];
var inner = customButton.$table;
var btnWrapper = $("em", inner);
var $input = $("input", btnWrapper);
var page=$input.val();
var total=$("tr[tridx=0]","div.content-container").children().eq(2).html();
if (total>parseInt(total)){total=parseInt(total)+1;
}
if(parseInt(page) > parseInt(total) || parseInt(page) < parseInt(1) )
{
alert("你输出的页数不再指定范围内");
}
else
window.location.href="${servletURL}?viewlet=报表.cpt&op=write&page="+page
});
The fourth button page break: the total number of pages of the fifth button, no js event
The 6th button next page
var page= $("tr[tridx=0]","div.content-container").children().eq(1).html();
var total=$("tr[tridx=0]","div.content-container").children().eq(2).html();
//JQURUY取下一页和总页数
if (total>parseInt(total)){total=parseInt(total)+1;
}
//判断总页数是不是整数,不是加一
if(parseInt(page) > parseInt(total))
{
this.setEnable(false);
alert("页数超出指定范围内");
}
else
window.location.href="${servletURL}?viewlet=报表.cpt&op=write&page="+page
//如果下一页在这个范围就跳转到那里
7th button end page
var total=$("tr[tridx=0]","div.content-container").children().eq(2).html();
//取总页数。
if (total>parseInt(total)){total=parseInt(total)+1;
}
window.location.href="${servletURL}?viewlet=报表.cpt&op=write&page="+total
//判断总页数是不是整数,不是加一,并跳转到最后一页。
The third part shows the result:
