state

问题 So this problem may have a easy solution, but I'm stuck for the moment. After the last update (Woocommerce 3.3.5) I have a problem with the state field on the checkout page, because it is not mandatory and people just skip it. I really need this thing to be mandatory, because I have connected my website to the delivery company server through and API to send the order info directly to them. I tried adding this to my functions.php and the thing is that when I go to the checkout page, the field

问题 html: <a ui-sref="user.tools.selectedTemplate({provider: t.id})" target="_blank">{{t.name}}</a> Above code is in ng-repeat with many template links loaded with name and id so when i click each link , href will be updated with id number appended to selected template link. I am generating about ten templates with same controller. I am passing value in ui-sref from one state to another so i need dynamic templateUrl, i tried this link issue but i cant able to send stateparams since the main

问题 i am displaying a numeral keypad in on a winform to enter code. i am displaying nummpad with buttons...

问题 I'm using react and I have some methods to set the state of my COmponent separately. I have the following methods: setLineColor(value){ this.setState({stroke:value},()=>{ this.props.data(this.getStyleData()); }); } setFillColor(value){ this.setState({ fill:value},()=>{ this.props.data(this.getStyleData()); }); } setMode(value){ this.setState({ mode:value},()=>{ this.props.data(this.getStyleData()); }); } How can I combine the methods, so that I can have something like: setAttribute(propery

问题 I am building the UI of an app and I am exploring updating the UI without having to use States. Would the following assertion be crudely correct? 'We do not need States as all its doing is calling the render method automatically on the component when something within the state changes. We can achieve the same implementation by calling the render method on the relevant component ourselves. We would still achieve all the same benefits of React (virtual DOM, rendering, painting optimisations etc

问题 I am having issues getting a delete dispatch event to work. I am trying to remove a list item from state. The error I get is the following: Error: Invalid value of type object for mergeProps argument when connecting component Invoices. I am new to redux and have tried various different approaches. From what I can tell, Redux is throwing an error in the following lines on Invoices.js export default connect( mapStateToProps, mapDispatchToProps, { getInvoices } )(Invoices); If I take out

问题 Hi I am just starting to learn angular && angular-ui-router and am trying to figure out how to determine when the app is opened for the first time to send the user to the login page or home page.

问题 Hello My application works like this. StartUpActivity is called first, which does a lot of the init stuff Then it launches TvbTabActivity (TabActivity) that has other Activities as its tabs (e.g. BrowseActivity). The problem that I am seeing is this - when a task-killer app is used to terminate my app on TvbTabActivity/Browse tab, and the app is relaunched again, the system forgoes the normal flow (StartUpActivity is not spawned), but instead restores the last visible activity directly

问题 REST advocates web applications without client state on the server. The famous shopping cart example is translated to a resource which typically resides in a database. I wonder if it is a good practise to use a database for that kind of data, since the database is already the bottleneck in many applications. Wouldn't it be better to use a stateful enterprise java bean instead? Application servers are designed with clustring in mind. What are the advantages and disadvantages of the two
