.substring错误:“不是函数" [英] .substring error: "is not a function"
问题描述
我不明白为什么我使用substring方法声明变量时收到错误消息.
I don't understand why I get an error message using the substring method to declare a variable.
我想在比较中使用URL的第一部分.
I want to use the first part of the URL in a comparison.
站点: http://www.elizabet.nl/wordpress
这是出问题的部分:
var currentLocation = document.location,
muzLoc = currentLocation.substring(0,45),
prodLoc = currentLocation.substring(0,48),
techLoc = currentLocation.substring(0,47);
错误:"currentLocation.substring不是函数"
The error: "currentLocation.substring is not a function"
但是这部分代码很好:
var URL = $(this).attr("href").substring(2) + ' #main';
所有代码:
jQuery(function($){
var siteURL = "http://" + top.location.host.toString() + "/wordpress", // Declareren van URL van de website.
URL = '', // Declareren van een URL, welke dan ook.
currentLocation = '',
muzLoc = '',
prodLoc = '',
techLoc = '',
allLinks = $('a[href^=' + siteURL + ']' ), // Declareren van alle menu-links. Het teken ^ betekent 'begint met'.
otherLinks = $('a[href^=' + siteURL + "/wp-content" + ']'),
siteLinks = $(allLinks).not(otherLinks),
mainDiv = $("#content"),
hash = window.location.hash,
muziekURL = "http://www.elizabet.nl/wordpress/#/muziek_pf/",
productieURL = "http://www.elizabet.nl/wordpress/#/productie_pf/",
techniekURL = "http://www.elizabet.nl/wordpress/#/techniek_pf/";
if (hash) {
hash = "/wordpress" + hash.substring(1); // substring methode haalt karakters van je string af. In dit geval de #, vanwege de offset=1.
URL = hash;
$(mainDiv).load(URL);
}
function pageLoad() {
var allLinks = $('a[href^=' + siteURL + ']' ),
otherLinks = $('a[href^=' + siteURL + "/wp-content" + ']'),
siteLinks = $(allLinks).not(otherLinks);
siteLinks.each(function() {
$(this).attr("href", "#" + this.pathname.substring(10));
})
.click(function() {
var URL = $(this).attr("href").substring(2) + ' #main';
$(mainDiv).load(URL, function(){
var currentLocation = document.location,
muzLoc = currentLocation.substring(0,45),
prodLoc = currentLocation.substring(0,48),
techLoc = currentLocation.substring(0,47);

推荐答案
document.location
是一个对象,而不是字符串.它返回(默认情况下)完整路径,但实际上包含的信息更多.
document.location
is an object, not a string. It returns (by default) the full path, but it actually holds more info than that.
解决方案的快捷方式: document.location.toString().substring(2,3);
Shortcut for solution: document.location.toString().substring(2,3);
或使用 document.location.href
或 window.location.href
