触发输入文件在第一页上的模式上单击不会触发

[英]trigger input file click on modal on first page load doesn't fire

使用angularJS,我有一个模式,该模式应触发输入文件以上传文件。

这是触发点击的功能

function triggerUploadMethod()
{
    inputFile = document.createElement('input');
    inputFile.type = 'file';
    inputFile.onchange = photoChosen;
    inputFile.click();
}

让我感到无聊的是,在第一个页面加载中,当我打开模式时,不会触发触发器。 如果我关闭模式并再次打开,则触发WORKS,它将一直工作到下一个页面加载...在第一个页面加载上不起作用怎么办?

这仅在Chrome上发生。 在Firefox,Edge和Internet Explorer上,即使页面加载后,触发器也每次都起作用。

作为免责声明,我从未使用过Angular,并且由于您未提供其他任何代码,因此我使用了香草JavaScript。

据我所知,代码中的错误与您上面发布的内容无关。 在下面的代码片段中,我从W3Schools的“如何使用CSS和JavaScript制作模态框”中获取了代码,然后将您的函数添加到了单击按钮即可打开模态的部分,并且可以正常工作(我在Chrome上)。

 // Get the modal var modal = document.getElementById('myModal'); // Get the button that opens the modal var btn = document.getElementById("myBtn"); // Get the <span> element that closes the modal var span = document.getElementsByClassName("close")[0]; // This variable isn't defined in your code so I just assume // it's somewhere at the top. var inputFile; // When the user clicks on the button, open the modal. // Also creates your input and clicks it. btn.onclick = function() { modal.style.display = "block"; triggerUploadMethod(); } // When the user clicks on <span> (x), close the modal span.onclick = function() { modal.style.display = "none"; } // When the user clicks anywhere outside of the modal, close it window.onclick = function(event) { if (event.target == modal) { modal.style.display = "none"; } } // Create the input element and click it. function triggerUploadMethod() { inputFile = document.createElement('input'); inputFile.type = 'file'; // I have no idea what this is so I can't include it. //inputFile.onchange = photoChosen; inputFile.click(); } 
 /* The Modal (background) */ .modal { display: none; /* Hidden by default */ position: fixed; /* Stay in place */ z-index: 1; /* Sit on top */ left: 0; top: 0; width: 100%; /* Full width */ height: 100%; /* Full height */ overflow: auto; /* Enable scroll if needed */ background-color: rgb(0,0,0); /* Fallback color */ background-color: rgba(0,0,0,0.4); /* Black w/ opacity */ } /* Modal Content/Box */ .modal-content { background-color: #fefefe; margin: 15% auto; /* 15% from the top and centered */ padding: 20px; border: 1px solid #888; width: 80%; /* Could be more or less, depending on screen size */ } /* The Close Button */ .close { color: #aaa; float: right; font-size: 28px; font-weight: bold; } .close:hover, .close:focus { color: black; text-decoration: none; cursor: pointer; } 
 <!-- Trigger/Open The Modal --> <button id="myBtn">Open Modal</button> <!-- The Modal --> <div id="myModal" class="modal"> <!-- Modal content --> <div class="modal-content"> <span class="close">&times;</span> <p>Some text in the Modal..</p> </div> </div>
