deferred

问题 This is the situation: I have two tables where the one references the other (say, table2 references table1). When creating these tables, I did set the foreign key constraint as DEFERRABLE and the ON UPDATE and ON DELETE clauses as NO ACTION (which is the default). But still, when running the transaction below, I get the following error. Transaction: START TRANSACTION; SET CONSTRAINTS ALL DEFERRED; UPDATE table1 SET blah blah; UPDATE table2 SET blah blah; COMMIT; Error: ERROR: update or delete

问题 First I enqueue a script using: wp_enqueue_script( "script", plugins_url( "/test/js/script.js", PATH ), array("jquery"), VERSION, true ); Then I'm inserting an inline script after "script". wp_add_inline_script( "script", "console.log('hello world');" ); Now I need to add defer or async attribute to my inline script, is there a way to do this to a script embedded by wp_add_inline_script() ? 回答1: wp_enqueue_script( "script", plugins_url( "/test/js/script.js", PATH ), array("jquery"), VERSION,

问题 I need to use defer to free allocations manually created using C library, but I also need to os.Exit with non 0 status at some point. The tricky part is that os.Exit skips any deferred instruction: package main import "fmt" import "os" func main() { // `defer`s will _not_ be run when using `os.Exit`, so // this `fmt.Println` will never be called. defer fmt.Println("!") // sometimes ones might use defer to do critical operations // like close a database, remove a lock or free memory // Exit

问题 I have a JSON object, which includes other objects and list of objects. Have to write a function, which iterates through all properties of objects as well as object within object and list of objects and replace null with an empty string. As it is loop inside loop, I need to implement deferred so sequential processing. I tried many ways, but failed. Anyone please help. function ValidateObject(result) { var aObj = result.A; aObj = VerifyForNull(aoBJ); var bObj = result.B; bObj = VerifyForNull

问题 I wrote some code below that uses promises and the easiest way I could find to write it was using a Deferred object instead of the usual Promise executor function because I need to resolve the promise from outside the executor. I'm wondering if there's an accepted design pattern based on the Promise executor function for a problem like this that doesn't use a deferred-like solution? Can it be done without having to resolve the promise from outside the promise executor? Here are the details. I

问题 1. Using es6 promise, but the syntax is incorrect. I'm using es6, and want to make a deferred confirm dialog: // First, create an empty promise: let promise = new Promise((resolve, reject) => {}) // Then, show the dialog: let $dialog = $('#dialog-confirm').show(); // FAIL: I want to trigger the promise resolver, but failed. $dialog.find('.btn-yes').click(() => { promise.resolve(); }) $dialog.find('.btn-no').click(() => { promise.reject(); }) When I clicked the button, it failed, because the

问题 Hoping some of you may help me with this problem. I have a few navigation link on top of my application which have active and not-active state. In theory, I want to jump from one to another and if there exists a form which isn't complete/valid, I trigger validation errors and stay on the same page. What is happening in my case is form validation works fine but navigation links on top change state from non-active to active, whichever was clicked. I have a ValidateForm function that validates

问题 Is it possible to call a Fortran subroutine from C/C++, where one of the Fortran arguments is a deferred-shape array? (Hopefully I'm using the term "deferred-shape" correctly.) In the example below, subr1() uses explicit-shape, and works fine, but subr2() uses deferred-shape and causes a segfault. This question indicates that one needs an explicit interface to call subr2() from another Fortran subroutine, but I'm trying to call from C. Is it just not possible to do it this way? In the real

问题 I have searched extensively and can not find an answer that seems to work. I have tried Q.deferred, async.series, async.each, I can not seem to get this sucker to work: Here is the code, this works, however, the "return subTree" fires for the "tree" export before the recursive is complete. I have validated that the recursive is digging appropriately. I really need the return on recuriveChildren to wait until the recursion call is complete. exports.tree = function(req, res) { var tree = {
