^ _ ^, Learn JavaScript, move up and down rows, use js to save the data to the XML file, and then read the XML on the server side and save it to the database.

}

// * Innerhtml,... difference

Innerhtml sets or obtains the HTML in the start and end tags of an object.
Outerhtml sets or obtains the HTML format of the object and its content
Innertext sets or obtains the text in the object's start and end labels.
Outertext setting (including tags) or obtaining (excluding tags) the text of an object
Innertext and outertext are the same when reading and obtaining data, but when you set them, outertext will replace them with tags to the target text.
Firefox does not support innertext, but textcontent can be used as an alternative.

// Test

<Div id = "Div"> <font color = "green"> <H2> This Is A Div! </H2> </font> </div>
<Input name = "innerhtml" value = "innerhtml" type = "button" onclick = "alert (div. innerhtml); "> // Result:"> <font color = "green"> <H2> This Is A Div! </H2> </font>

<Input name = "outerhtml" value = "outerhtml" type = "button" onclick = "alert (div. outerhtml); "> // result: <Div id =" Div "> <font color =" green "> <H2> This Is A Div! </H2> </font> </div>

<Input name = "innertext" value = "innertext" type = "button" onclick = "alert (Div. innertext);">
<Input name = "outertext" value = "outertext" type = "button" onclick = "alert (Div. outertext);">
