Append Multiple Items In JavaScript


Answer :

You can do it with DocumentFragment. 

var documentFragment = document.createDocumentFragment(); documentFragment.appendChild(listItem); listItem.appendChild(listItemCheckbox); listItem.appendChild(listItemLabel); listItem.appendChild(editButton); listItem.appendChild(deleteButton); listElement.appendChild(documentFragment);

DocumentFragments allow developers to place child elements onto an arbitrary node-like parent, allowing for node-like interactions without a true root node. Doing so allows developers to produce structure without doing so within the visible DOM


You can use the append method in JavaScript.

This is similar to jQuery's append method but it doesnot support IE and Edge.

You can change this code

listElement.appendChild(listItem); listItem.appendChild(listItemCheckbox); listItem.appendChild(listItemLabel); listItem.appendChild(editButton); listItem.appendChild(deleteButton);

to

listElement.append(listItem,listItemCheckbox,listItemLabel,editButton,deleteButton);

Personally, I don't see why you would do this.

But if you really need to replace all the appendChild() with one statement, you can assign the outerHTML of the created elements to the innerHTML of the li element.

You just need to replace the following:

  listElement.appendChild(listItem);   listItem.appendChild(listItemCheckbox);   listItem.appendChild(listItemLabel);   listItem.appendChild(editButton);   listItem.appendChild(deleteButton);

With the following:

listItem.innerHTML+= listItemCheckbox.outerHTML + listItemLabel.outerHTML + editButton.outerHTML + deleteButton.outerHTML; listElement.appendChild(listItem);

Explanation:

The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. So assigning the outerHTML of the created elements to the innerHTML of the li element is similar to appending them to it.

Chemistry - Bond Angles In NH3 And NCl3

Answer : Solution 1: As Tan Yong Boon stated, it is Bent’s Rule with which we can explain the lower bond angle of \ce N F 3 \ce{NF3} \ce NF 3 when compared to \ce N H 3 \ce{NH3} \ce N H 3 . The rule as stated by Henry Bent: Atomic s character concentrates in orbitals directed towards electropositive substituents. Fluorine is more electronegative that hydrogen, and the \ce N − F \ce{N−F} \ce N − F bond would have greater p character than the \ce N − H \ce{N−H} \ce N − H bond. And more s character leads to large bond angles. Thus, the bond angle is greater in \ce N H 3 \ce{NH3} \ce N H 3 than in \ce N F 3 \ce{NF3} \ce NF 3 . Now, consider \ce N C l 3 \ce{NCl3} \ce NCl 3 . Clearly, \ce C l \ce{Cl} \ce Cl atom islarger in size than the central atom, nitrogen. Hence the higher bond angle here is due to the steric crowding caused by \ce C l \ce{Cl} \ce Cl atoms.(More pronounced than the electrongativity of \ce C l \ce{Cl} \ce Cl atom). They repel eachother and hence b...

Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Answer : VACUUM is only needed on updated or deleted rows in non-temporary tables. Obviously you're doing lots of INSERTs but it's not obvious from the description that you're also doing lots of UPDATEs or DELETEs. These operations can be tracked with the pg_stat_all_tables view, specifically the n_tup_upd and n_tup_del columns. Also, even more to the point, there is a n_dead_tup column that tells, per table, how much rows need to be vacuumed. (see Monitoring statistics in the doc for functions and views related to statistics gathering). A possible strategy in your case would be to suppress the scheduled VACUUM, keeping an eye on this view and checking on which tables the n_dead_tup is going up significantly. Then apply the aggressive VACUUM to these tables only. This will be a win if there are large tables whose rows never get deleted nor updated and the aggressive VACUUM is really necessary only on smaller tables. But keep running the ANALYZE for the optimiz...

Change The Font Size Of Visual Studio Solution Explorer

Answer : Go to Tools->Options->Environment->Fonts and Colors In "Show Settings for" chose "Environment Font" In "Font" replace Automatic to for example, Arial and change size. Change the font size of that setting, all Font size in the Explorers (Solution Explorer, Server Explorer and Toolbox) and menus will change. You can set that in Tools, Options.
