问题 how can I make this possible? function _(element) { var el = document.querySelector(element); return el; } function colorize(color) { this.style.color = color; } _("#myElement").colorize("#f0f0f0"); that this code first gets the element and then changes its text color. How to make sth like this????? 回答1: _("#myElement") returns an instance of Element. You can add colorize property to Element.prototype . Now, all objects of type Element will be able to call it: function _(element) { var el =

问题 I am wondering using Angular, if the <input> has 'type' set to 'number', can you force a initial display of a non-number string if ng-model is initialized to certain number (0 in my example)? My example code is here: http://plnkr.co/edit/TwraJlxZSd3TeSYscExq?p=info This topic is related to: [1]: 'AngularJS directives to hide zero when <input> is initially loaded to the DOM' and: [2]: 'Hide Value in input when it's zero in angular Js' 回答1: The following directive will solve your problem, app

问题 var otbody = document.createElement('tbody'); var otr = otbody.insertRow(ordernumber); otr.id="order" + ordernumber; var pidCell = otr.insertCell(0); There is an error when insertRow is executed in IE7. I use IE9's IE7 mode, and otbody does have the method insertRow. I have tried 0, -1, 1 etc. as the argument of this method in debugger console, but all return null. And when I use document.createElement("tr") to create table row, insertCell() returns null. I wonder if these methods to deal

问题 I am trying to use reCaptcha on my site, and recaptcha_challenge_field, and recaptcha_response_field are not being added to the $_POST array on the backend - but the rest of the variables from my form are. Any ideas? I have double checked the public/private keys. Here is the generated HTML: <form action='myform.php' name='myform' id='myform' method='post' enctype='multipart/form-data'> <tr class='select'> <td class='label'>Name:</td> <td> <input type='text' name='name' id='name' class=

问题 I have a React-Leaflet map which I am rendering a div inside. For some reason, interacting with the contents of the div causes the map beneath to respond (eg: double-clicking will zoom the map, dragging will pan the map) - even when I'm calling e.stopPropagation() in handlers attached to the div. As I understand it, calling stopPropagation() should prevent the DOM events from ever reaching the map itself. Why does it appear that stopPropagation() is being ignored? How can I render a div

问题 I wonder if is it possible to refer to some elements using something like the Javascript DOM, without using Javascript or other programming languages. This is what I mean. Suppose that we have two divs that should have the same height. I would like to get the first div's height to assign this to the second one, like this : #div1 { height:400px; } #div2 { height:#div1.height; } As you can see, I'm doing exactly the same of document.getElementById("id").style.height in Javascript. Is it
