[英]Should raw javascript be in a .js file - How to include?
Suppose I have a page such as the following 假设我有一个如下的页面
<html><head></head><body><!--STUFF-->
<script>
if(SomeBooleanVariable) {
$.getScript('js/file.js');
}
</script>
</body></html>
and my file.js file simply contains raw jQuery events with no wrapping. 而我的file.js文件仅包含原始jQuery事件,没有任何包装。 It is exactly as follows:
内容如下:
$(document).on("eventHere", "classHere", function(e) {
//Stuff
});
$(document).on("eventHere", "classHere", function(e) {
//Stuff
});
This is simply not working. 这根本行不通。 When I include the contents of file.js directly into the HTML it works fine however the JS does not seem to be included properly.
当我将file.js的内容直接包含到HTML中时,它可以正常工作,但是JS似乎未正确包含。 I have tried putting "alert(3);"
我试过把“ alert(3);” at the top of file.js but it does not fire.
在file.js的顶部,但不会触发。 I have tried the following:
我尝试了以下方法:
$("head").append("<script src=\"js/file.js\" />");
$(document).append("<script src=\"js/file.js\" />");
-and-
document.write("<script src=\"js/file.js\" />");
If you want to load that .js file dynamically, change your code to this: 如果要动态加载该.js文件,请将代码更改为此:
if(SomeBooleanVariable) {
$.getScript("ajax/test.js")
.done(function(script, textStatus) {
console.log(textStatus);
})
.fail(function(jqxhr, settings, exception) {
console.log("Triggered ajaxError handler.");
});
And see if you get any error in console 看看您是否在控制台中遇到任何错误
It may be, that you are, for example, using mod_rewrite and jQuery tries to load script relative to the "folder" your subpage is in. Example: you are @ http://www.example.com/link-to-subpage/ . 例如,您可能正在使用mod_rewrite,而jQuery尝试加载相对于您子页面所在的“文件夹”的脚本。示例:您位于@ http://www.example.com/link-to-subpage / 。 In this case, jQuery will try to load http://www.example.com/link-to-subpage/js/file.js , while it resides @ http://www.example.com/js/file.js .
在这种情况下,jQuery将尝试加载http://www.example.com/link-to-subpage/js/file.js ,而它驻留@ http://www.example.com/js/file.js 。 In this case, use an absolute path.
在这种情况下,请使用绝对路径。 So, instead of:
因此,代替:
js/file.js
write: 写:
/js/file.js
