[英]What is wrong with my Javascript?
This is my jsfiddle(http://jsfiddle.net/mZGsp/). 这是我的jsfiddle(http://jsfiddle.net/mZGsp/)。 I was trying to answer a question here but my code won't work.
我试图在这里回答一个问题,但是我的代码无法正常工作。 Here is the code:
这是代码:
var stateOfClick = null;
function initiateLine(){
document.getElementById('test').innerHtml = "Started";
}
function endLine(){
document.getElementById('test').innerHtml = "Line Ended";
}
function createLines(){
if(!stateOfClick) {
initiateLine();
stateOfClick = 1;
} else {
endLine();
}
}
<body>
<input type="text" id="test" onclick="createlines()">
</body>
A couple of things, 有几件事,
createlines()
to createLines
(camel-case). createlines()
到createLines
(骆驼情况)。 <element>.innerHtml
to <element>.value
<element>.innerHtml
更改为<element>.value
createLines
won't be global which it needs to be for the onclick
to work. createLines
不会是全球性的,它需要成为的onclick
工作。 Not even this simple example will work on jsFiddle. 即使这个简单的示例也无法在jsFiddle上运行。 You need to attach the event listener with JavaScript:
您需要使用JavaScript附加事件监听器:
document.getElementById("someElement").onclick = function() {
//Do stuff
}
For input element you must use the value attribute not the innerHTML field. 对于输入元素,必须使用value属性,而不是innerHTML字段。
function initiateLine(){
document.getElementById('test').value = "Started";
}
also you've misspelled the innerHTML function (though not the primary problem). 您也拼错了innerHTML函数(尽管不是主要问题)。 innerHTML is used for html elements that can contain other elements such as a div containg ap element.
innerHTML用于可包含其他元素(例如div containsg ap元素)的html元素。 Input and option elements all have a value attribute that can be used to extract or set their values.
输入元素和选项元素均具有值属性,可用于提取或设置其值。
