If you just need to test basic equality, this can be done with the basic JDK without modifying the input lists in the one line !Collections.disjoint(list1, list2); If you need to test a specific property, that’s harder. I would recommend, by default, list1.stream() .map(Object1::getProperty) .anyMatch( list2.stream() .map(Object2::getProperty) .collect(toSet()) ::contains) …which collects the distinct values in … Read more
var eElement; // some E DOM instance var newFirstElement; //element which should be first in E eElement.insertBefore(newFirstElement, eElement.firstChild);
I can suggest 2 ways. First way define your variables before call the javascript, inside the .aspx file that can be compiled. var ButtonXXXID = <%=buttonXXX.ClientID%> // and now include your javascript and use the variable ButtonXXXID Second way in the external javascript file, write your code as: function oNameCls(ControlId1) { this.ControlId1 = ControlId1; this.DoYourWork1 … Read more
There is no consensus on best practice, and according to the author of the spec, Ian Hickson, it does not matter.
appendChild will remove the node from wherever it is before appending it to its new location, so you need to make copies of the node instead. You can use cloneNode for that. The true makes cloneNode perform a deep clone, i.e. with all its child nodes. for(var i = 0; i < urls.length; i++){ sliderBody.appendChild(slide.cloneNode(true)); … Read more
In this case you need to go up to the <tr> then use .next(), like this: $(obj).closest(‘tr’).next().find(‘.class’); Or if there may be rows in-between without the .class inside, you can use .nextAll(), like this: $(obj).closest(‘tr’).nextAll(‘:has(.class):first’).find(‘.class’);
You can do: keys <- unique(c(names(lst1), names(lst2))) setNames(mapply(c, lst1[keys], lst2[keys]), keys) Generalization to any number of lists would require a mix of do.call and lapply: l <- list(lst1, lst2, lst1) keys <- unique(unlist(lapply(l, names))) setNames(do.call(mapply, c(FUN=c, lapply(l, `[`, keys))), keys)
You can create a temporary parent node, and get the innerHTML content of it: var el = document.createElement(“p”); el.appendChild(document.createTextNode(“Test”)); var tmp = document.createElement(“div”); tmp.appendChild(el); console.log(tmp.innerHTML); // <p>Test</p> EDIT: Please see answer below about outerHTML. el.outerHTML should be all that is needed.
Update: The question was edited. Both of the solutions are now equivalent. Original answer Yes, most notably! I don’t think the second one will work (and if it does, not very portably). The first one should be OK. // HTML: <input id=”theId” value=”test” onclick=”doSomething(this)” /> // JavaScript: function(elem){ var value = elem.value; var id = … Read more
Use count() twice; one time in default mode and one time in recursive mode. If the values match, the array is not multidimensional, as a multidimensional array would have a higher recursive count. if (count($array) == count($array, COUNT_RECURSIVE)) { echo ‘array is not multidimensional’; } else { echo ‘array is multidimensional’; } This option second … Read more
