[英]Calling JavaScript function into a P tag
I would like to call the following javaScript function so it gets outputted to a HTML P tag, but am not sure how to do this without explicitly calling the function in the HTML file. 我想调用以下javaScript函数,以便将其输出到HTML P标记,但不知道如何在不显式调用HTML文件中的函数的情况下执行此操作。
I do not want to do this... 我不想这样做......
<p class="showcode">
<script type="text/javascript">
wise_words();
</script>
</p>
I would like to keep the javaScript code all in one js file. 我想将javaScript代码保存在一个js文件中。
I have tried it this way but this does not seem to work... 我试过这种方式,但这似乎不起作用......
document.getElementById("showcode").innerHTML = wise_words();
I would really appreciate any help as to what I am doing wrong. 对于我做错了什么,我真的很感激。
Here is my code... http://codepen.io/anon/pen/qfLdE I would like to have the generated text get outputted inside the grey box. 这是我的代码... http://codepen.io/anon/pen/qfLdE我想让生成的文本在灰色框内输出。
You should call the function in an onload
handler, so that it is executed after the DOM has been constructed: 您应该在onload
处理程序中调用该函数,以便在构造DOM之后执行它:
window.onload = function() {
document.getElementById("showcode").innerHTML = wise_words();
}
Another problem is that your wise_words()
function is using document.write
(please don't use document.write
) instead of returning a value. 另一个问题是你的wise_words()
函数正在使用document.write
(请不要使用document.write
)而不是返回一个值。 You need to return a value: 您需要返回一个值:
var retText = wiseText[nextVal][0];
nextVal += 1;
writeCookie("wisewords", nextVal.toString(), 33);
return retText;
Try following using Jquery: 尝试使用Jquery:
$(".showcode").html(wise_words());
NOTE: Assuming your function returns the HTML/text. 注意:假设您的函数返回HTML /文本。
<p class="showcode">
<script type="text/javascript">
document.write(wise_words());
</script>
</p>
or: 要么:
<body onload="document.getElementById('showcode').innerHTML = wise_words()">
<p id="showcode">
</p>
</body>
(note id
instead of class
). (注意id
而不是class
)。
