I am developing a notepad app at Monaca.
I made it based on the Notepad app template, but the template did not have the ability to edit notes.
Therefore, I tried to add the editing function as below, but when I went to the editing screen, the original memo content was not displayed.
In detail, when you first press the Edit button after registering a memo, the original memo is not displayed, but when you re-enter it and press Save Overwrite, the next time you edit it, the re-enter it will appear properly.
Perhaps the description around onShowLink is insufficient, but I would appreciate it if you could tell me how to improve it.
Thank you for your cooperation.

///// Initialize top page

}
if(list.length==0){
$li = $("<li> No Notes </li>");
$("#TopListView").prepend($li);
}
$("#TopListView").listview("refresh");// Call refresh after manipulating list
}
///// Move to detail page
function onShowLink() {
var$li=$(this).parent();
selectedMemoId=$(this).parents('li').data("id");
varmemoTitle=$li.find("h3").text();
varmemoHtml=$li.find("p").html().replace(/\n/g, "<br>");
$("#ShowPageh1").text(memoTitle);
$("#ShowPagep").html(memoHtml);
$.mobile.changePage("#ShowPage");
}
///// Delete memo
function onDeleteLink(){
if(!confirm("Do you want to delete this note?")) {
return;
}
var$li=$(this).parent();
variable = $li.data("id");
deleteMemo(id);
initTopPage();
// Return to top
$.mobile.changePage("#TopPage", {reverse:true});
}
///// Called when app launch
function onReady() {
initTopPage();
$("#SaveBtn").click(onSaveBtn);
$("#TopListView").on("click", "a.show", onShowLink);
$("#TopListView").on("click", "a.delete", onDeleteLink);
}
///// Edit memo
function saveEditedMemo(){
variableText=$("#EditPage input#edit") .val();
if(editedText!='){
deleteMemo(selectedMemoId);
addMemo(editedText);
// Clear form
$("#Memo").val("";
// Initialize top page
initTopPage();
}
$.mobile.changePage("#TopPage", {reverse:true});
}
$(onReady); // on DOMContentLoaded
I changed onShowLink() to the following and it appeared.
However, it is uncomfortable to set the value of EditPage when displaying ShowPage, so I thought it would be better to prepare another function.
// Move to detail page
function onShowLink() {
var$li=$(this).parent();
selectedMemoId=$(this).parents('li').data("id");
varmemoTitle=$li.find("h3").text();
// Before the change
// varmemoHtml=$li.find("p").html().replace(/\n/g, "<br>");
// after modification
varmemoContent=$li.find("p").html();
varmemoHtml=memoContent.replace(/\n/g, "<br>");
$("#ShowPageh1").text(memoTitle);
$("#ShowPagep").html(memoHtml);
// Add 1 sentence below
$("#EditPage input#edit").val(memoContent);
$.mobile.changePage("#ShowPage");
}
The next time you edit it, you'll see what you've re-entered
As for this, I think there is probably a cache left when editing.
