I want to send NewIDs in my database. According to the title of each click, send the corresponding NewIDs to the new page, and then the new page will accept it. It will also be displayed using datalist. How should the code be implemented? Specifically, it is the part that receives and displays the details.

Answer 1

To achieve clicking on each title to enter the corresponding page number can be achieved by setting the click event of the datalist in ASPNet.

First, add a datalist control to the ASPNet page and set a unique ID in its ID property.

Next, add a click event processor in the code to respond to the click event of the datalist control. In this processor, you can get all the title's page number elements in the datalist control and use the javelin's DOM operation to get the corresponding page number elements. Then, you can combine them together to create a new page number element and add this element to the datalist control's page number element.

For example, if the ID of the datalist control is myDatalist, the title is novel 1, and the page number is 1:

```
datalist1DatalistClick += new SystemWebUIDataListClickHandler(datalist1_DataListClick);

private void datalist1_DataListClick(object sender SystemWebUIDataListClickEventArgs e)
{
string title = datalist1DataListUrlToString();
string ep code = datalist1DatalistUrlSegments[datalist1DatalistUrlSegmentCount - 1];
&lt;strong&gt;&lt;/strong&gt;&lt;strong&gt;&lt;/</a>strong&gt;<br>;
datalist1HTML += html;
}
```

In the code above, we use the `DatalistClickListener` event processor to handle the click event of the datalist control. In this processor, we first get all the title's browser elements in the datalist control and then use the javelin's DOM operation to get the corresponding page number element. Next, we use string stitching to combine the title and page number elements together and add them to the datalist control's browser element.

Finally, in the page's javelin code, we can use the `documentgetElementByID()` method to get the datalist control's browser element, then use the `documentqueryListener ()` method to get the title element, and use the javelin's DOM operation to get the corresponding page number element, then combine them together to create a new browser element and add it to the datalist control's browser element.

For example, if the ID of the datalist control is myDatalist, the title is novel 1, and the page number is 1:

```
<script>
var title = documentgetElementById(myDatalist)innerHTML;
varep code = documentgetElementByID(myDatalist)Segments[1];
&lt;strong&gt;&lt;/strong</a>&gt;<br>;
documentgetElementById(myDatalist)innerHTML = html;
</script>
```

In the code above, we use the javelin's DOM operation to get the datalist control's hr element, then use the `innerml` attribute to update it to the title and page number element's hr string, and finally add them to the datalist control's hr element.

This way, when the user clicked on the title in the datalist control, they would enter the corresponding page number.
