由 ＊爱你＆永不变心＊ 提交于 2019-12-19 07:06:16
问题 I can't clearly understand the differences between using //element and /descendant::element when selecting multiple children of a base element in XPath. Given this HTML snippet <html> <body> <div class="popupContent"> <table> <tr class="aclass"><td> Hello </td> <td> <input type="text" value="FIRST" /> </td></tr> <tr class="aclass"><td> Goodbye </td> <td> <input type="text" value="SECOND" /> </td></tr> </table> </div> </body> </html> I need to select each input based on its positioning in the

How can I get the foreign keys of a table in mysql

由 ﹥＞﹥吖頭↗ 提交于 2019-12-18 17:18:38
问题 I am creating a class which, takes a table from a database, and displays it to a web-page, with as much functionality as possible. One of the things I would like to support, would be having the class detect which columns in the table have a foreign key constraint on them, so that it can then go to those tables, get all of their values and use them in a select-box which is called when you edit those fields, to avoid someone violating foreign key constraints, The main problem is discovering

Fork a child process and inject dependency

由 懵懂的女人 提交于 2019-12-18 13:10:00
问题 I currently have an operation in a module that is blocking, so I'm looking at making this into a child process that I fork instead. If I want to do that, then I of course need to modify the architecture of my module. The module requires that a dependency is injected by calling the module as a function, passing in the dependency, like so: var dependency = { name: "Bob" } require('worker')(dependency) Then in my worker module: module.exports = function (dependency) { // Outputs { name: "Bob" }

Get to get all child scopes in Angularjs given the parent scope

由 这一生的挚爱 提交于 2019-12-17 23:27:42
问题 I would like to know how to get a list of all child scopes given a parent scope. All I can find from the properties of the scope are $$childHead, $$childTail, $$nextSibling and $$prevSibling. The approach I'm using now is to get the childHead from the parent and then using the nextSibling to get the next child until nextSibling is null. Is there a better approach? Given that I want to call a method [getModel] on all the children, is there again a better way of doing this? 回答1: The child

Why is forEach not working for children?

由 China☆狼群 提交于 2019-12-17 23:26:37
问题 I have a <div> with some child <div> in it. E.g. <div id="niceParent"> <div></div> <div></div> <div></div> <div></div> </div> I tried to loop through them with the forEach function, because I thought that document.getElementById("niceParent").children is an array, as I can access the elements with console.log(document.getElementById("niceParent").children[1]); console.log(document.getElementById("niceParent").children[2]); console.log(document.getElementById("niceParent").children[3]);

Hiding Options of a Select with JQuery

由 馋奶兔 提交于 2019-12-17 20:45:36
问题 Okay, let's start with an example. Keep in mind, this is only an example. <select id = "selection1"> <option value = "1" id = "1">Number 1</option> <option value = "2" id = "2">Number 2</option> <option value = "3" id = "3">Number 3</option> </select> Now from here, we have a dropdown with 3 options. What I want to do now is to hide an option. Adding style = "display:none" will not help. The option would not appear in the dropdownlist, but using the arrow keys, you can still select it.
