try-wrapper | 通过构建用try-catch将函数包裹起来

I've this structure here build from a previous question:

In the case that I am fetching Country and State data from an API, I can't seem to keep the link to the model after updating a kendo combobox's data source.

Let's say that there is a form that will be used internationally. So we want to provide a Country Combobox and a State Combobox and then filter the state by the selected country. If the user selects a country, then the state combobox updates. This is great! However, when I go to submit, the stateid field in the model is null.

I've tried manually changing the datasource, and can't really find any more information on this kind of issue. If anyone can point me in the right direction, that would be greatly appreciated.

Data model:

I am trying to use d3.select(this) and this.data_ in this.HandleMouseOver. I have tried various ways to fix the issue such as converting .on('mouseover', this.handleMouseOver); to .on('mouseover', function(){ this.handleMouseOver(d3.select(this), this.data_); }); // >> error: this.handleMouseOver is not a function - but no luck so far (yes, I added the inputs on handleMouseOver(selection,data).

Any suggestions on how I can access d3.select(this) and this.data_ in handleMouseOver()?

I am trying to transition only the textpath on which I am mousehovering but both textpaths in the example below get transitioned. Is there a way to only transition the one when hovering?

For the code below I modified this example and I am using version 5 of D3.js.

Here is the script:

I am trying to add multiple shortcode generate blog post loops to one page

Problem: when i add two shortcodes including blog post loop to one page, the shortcode plants itself inside the first shortcodes outer div, this happens to some of my php code as well, perhaps you can save the day, by spotting the error?

Here you will see, that the second row (this is where the second loop from shortcode starts, the row is wider, which essentially is the problem):

If I were to add another loop with same build of shortcode, it would be wider than the second and so on..

The html output, here you can see that the second loops has implanted itself into first loops "row". https://ibb.co/h7pOpb
