Check multiple-selection and batch deletions in input report

Background
For users of report, efficiency is very important. However, sometimes users have to do some simple operation time and again.

For example, there are a lot of data on a web page when making a row input report. Users may want to delete the data of 28 rows. If they have to click the “Delete” button every time when they delete a row, the page will be refreshed 28 times. That’s very inefficiency.

Then, how to solve it?

Solution
http://www.raqsoft.com/ (RAQ Report) is a pure Web-based Java reporting tool. As it is a professional Web reporting tool, RAQ Report can help users to achieve batch selection and deletion in a row input easily.

Operation
With RAQ Report, you only need 4 steps.

Step 1: Design the report as shown below:

Note: A2 is set as checkbox. Set “Off” 0 and “On” 1.

Step 2: In the jsp file, add batch deletion javascript as follows:

function deleteRows(){
var report = document.getElementById('report1′);
for(var i=report.rows.length-2;i>0;i-){
var row = report.rows[i];
if(!row.all.tags("input")[0].checked) continue;
var cell = row.cells[1];
report.currCell = cell;
_deleteRow(report);
}
}
Step 3: In the jsp file, add checkbox javascript as follows:

function selcheck() {
var objs = report1.getElementsByTagName("input");
for(var i=0; i<objs.length; i++) {
if(objs[i].type.toLowerCase() == "checkbox" )
objs[i].checked =event.srcElement.checked;
}
}
Step 4: In the jsp file, add operating button javascript as follows:

<table>
<tr>
<td style="background-color:">
<div noWrap style="font-family: Ming;font-size:13px;color:;">
Select all:<INPUT type="checkbox" onclick="selcheck()">
<span style="cursor:pointer" onclick="_insertRow( report1 )">Insert</span>
<span style="cursor:pointer" onclick="_appendRow( report1 )">Add</span>
<span style="cursor:pointer" onclick="deleteRows()">Delete</span>
<span style="cursor:pointer" onclick="_submitRowInput( report1 )">Submit</span>
</div>
</td>
</tr>
</table>
