我只是想知道如何使用JavaScript来模拟对元素的单击。
目前我有:
function simulateClick(control) {
if (document.all) {
control.click();
} else {
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window, 1, 12, 345, 7, 220, false, false, true, false, 0, null );
control.dispatchEvent(evObj);
}
}
<a href="http://www.google.com" id="mytest1">test 1</a><br>
<script type="text/javascript">
simulateClick(document.getElementById('mytest1'));
</script>
但它并没有起作用:(
什么好主意吗?
这没有很好的记录,但我们可以非常简单地触发任何类型的事件。
这个例子将触发50双击按钮:
let theclick = new Event(“dblclick”)
for (let i = 0;i < 50;i++){
action.dispatchEvent(theclick)
}
<button id=“action” ondblclick=“out.innerHTML+='Wtf '”>TEST</button>
<div id=“out”></div>
The Event interface represents an event which takes place in the DOM.
An event can be triggered by the user action e.g. clicking the mouse
button or tapping keyboard, or generated by APIs to represent the
progress of an asynchronous task. It can also be triggered
programmatically, such as by calling the HTMLElement.click() method of
an element, or by defining the event, then sending it to a specified
target using EventTarget.dispatchEvent().
