javascript cloneNode and properties

由 独自空忆成欢 提交于 2019-12-30 15:02:51
问题 Is there a quick way to "super" deep clone a node, including its properties? (and methods, I guess) I've got something like this: var theSource = document.getElementById("someDiv") theSource.dictator = "stalin"; var theClone = theSource.cloneNode(true); alert(theClone.dictator); The new cloned object has no dictator property. Now, say I've got a thousand properties attached to theSource - how can I (non-explicitly) transfer/copy them to the clone? // EDIT @Fabrizio Your hasOwnProperty answer

问题 I have a documentFragment with several child nodes containing some .data() added like so: myDocumentFragment = document.createDocumentFragment(); for(...) { myDocumentFragment.appendChild( $('<a></a>').addClass('button') .attr('href', 'javascript:void(0)') .html('click me') .data('rowData', { 'id': 103, 'test': 'testy' }) .get(0) ); } When I try to append the documentFragment to a div on the page: $('#div').append( myDocumentFragment ); I can access the data just fine: alert( $('#div a:first'

JavaScript: cloneNode vs importNode

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-12 01:37:46
问题 I noticed in some code samples to seemingly different ways to clone a DOM node and append it to an existing element: element.appendChild(something.cloneNode(true)); element.appendChild(document.importNode(something, true)); Both have the effect of copying a node. The second version seems more verbose, and implies that the copy is actually somewhere concrete first, though it still needs to find a proper home. However, it is used by MDN and a few other as an illustration of using the template

Why does cloneNode exclude custom properties?

问题 This is related to the question javascript cloneNode and properties. I'm seeing the same behaviour. Node.cloneNode does not copy over any properties that I add myself (code from original post): var theSource = document.getElementById("someDiv") theSource.dictator = "stalin"; var theClone = theSource.cloneNode(true); alert(theClone.dictator); theClone does not contain any property "dictator". I haven't been able to find any explanation for why this is the case. The documentation on MDN states

问题 I'm trying to clone a div in pure Javascript, however, cloneNode leads to duplicate ids (div_0). I would like to increment the id as div_1, div_2... and do the same to somevar = {'elem', 'div_1'}... Thanks <html> <head></head> <body> <div id="mydiv"> <div id="div_0"> <script type="text/javascript"> <!-- somevar = {'elem', 'div_0'}; //--> </script> <p>HELLO</p> </div> </div> <a href="#" onclick="cloning()">CLONE</a> <script type="text/javascript"> function cloning() { var container = document

How to dynamically add a cloned node in angular2 (equivalent to cloneNode)

由 こ雲淡風輕ζ 提交于 2019-12-01 11:13:42
In Angular2, I need to duplicate a node rather than moving it in some cases. That node has angular2 properties so cloneNode doesn't work. How can I do it? *what doesn't work let el = <HTMLElement>document.getElementById(divId); if ((<HTMLElement>el.parentNode).id == 'itsMe') el = <HTMLElement>el.cloneNode(true); document.getElementById(anotherId).appendChild(el); *what would work, from Angular2: Cloning component / HTML element and it's functionality @Component({ selector: 'my-app', template: ` <template #temp> <h1 [ngStyle]="{background: 'green'}">Test</h1> <p *ngIf="bla">Im not visible</p> <
