To map first: It can be found that when using parseint () to convert a string, only "08", "09" is converted to 0, and the other is converted to the corresponding number, what is the reason?Originally when the first string is "0", JS default it is 8, so the problem comes, 8 binary numbers only 0-7, so the previous 0-7 is no problem.However to 8 and 9 The problem came, 8 and 9 in the 8 binary is unqualified, so the output is 0.Workaround:Add the parsei

1.TableView with sliding delete function, as long as the method of implementing the Agent TableView:commitEditingStyle:forRowAtIndexPath: method can be done in the method of data manipulation, refresh the table on the line.2. There are two ways to refresh a table:
Tableview:reloadrowsatindexpath: This method is used only if the model data is consistent with the number of tableView rows.
Tableview:deleterowsatindexpath: This method is used only if the number of model data deletes is the

The update of the 3.SQLITE3 database and the order of delete operations are almost the same as creating the table, just change the next statement.The order of query statements for the 4.SQLITE3 database is more complex, as follows:

Defines a sqlite3_stmt pointer object;
Use SQLITE3_PREPARE_V2 (SQLite pointer object, SQL statement, 1 (length

They are equivalent to the functions in the Ko.observablearray, but they work with the object by key. For example:var obj = [ {id:1}, {Id:2}]var result = Ko.mapping.fromJS (obj, { Key:function (item) { Return ko.utils.unwrapObservable (item.id); }});Result.mappedremove ({id:2});Map over the observable array, in addition to the above function also supports a mappe
x = 0; xNotice the break in line 5th, which is the function of jumping out of the for loop, not the outside for loop. So the output is:If you change the position of the break1 for (int x = 0; xBREAK;7}Notice the break in line 6th, which is the function of jumping out of the for loop, not the for loop inside. So the output is:The rule is already obvious: break only affects the for loop where it resides.2.continueContinue can only be used in a looping structure, and its role is to skip this cycle

Learn from WPF 03: Element Binding: You can bind the control property to the control property.
Learn from WPF 07: Data Binding of MVVM preparation knowledge allows you to bind control attributes with custom object attributes.
The above two functions are not enough in practical application. We often need to bind the list data with the control attributes.
