如何在不创建页面重新加载的情况下更改Firefox window.location.hash?

问题描述：

我将一些状态信息存储在URL片段中(哈希，无论您叫什么).当我在Chrome和Safari中更改 window.location.hash 时，该页面不会重新加载-这是我想要的行为.当我在Firefox中更改 window.location.hash 时，我会重新加载页面.我该如何预防?

I'm storing some state information in the URL fragment (hash, whatever you call it). When I change the window.location.hash in Chrome, and Safari the page doesn't reload - this is the behavior I want. When I change window.location.hash in Firefox, I get a page reload. How do I prevent this?

注意:我在URL中存储状态的原因是为了使userA可以将URL发送给userB，而userB则可以看到同一页面(由AJAX加载).

解决方案:就其价值而言，如果您完全删除包含#"字符的哈希，则将在Firefox(仅?)中重新加载页面.我最后只是确保不要删除整个哈希.

Resolution: For what it's worth, in Firefox (only?) the page will reload if you completely remove the hash including the "#" character. I ended up just making sure not to delete the entire hash.

在您提到的帖子上，这是设置 hash 的代码:

On the post you mentioned, here's the code that sets the hash:

function (hsh) {
    hsh="#"+hsh;
    this.current.hash=hsh;
    document.location.hash=hsh;
}

这是读取 hash (例如从另一个URL)的代码:

function () {
    if(document.location.hash.split("#").pop()==this.current.hash.split("#").pop()) { return; }//this hash was set by code!
    var bl=-1;//-1 = none; otherwise, it's a block index.
    var cp=-1;
    if(document.location.hash.indexOf(Un.HASH_BLOCK_PREFIX)&gt;-1) {
        var blkhsh=document.location.hash.substring(Un.HASH_BLOCK_PREFIX.length+1);
        var blknum=parseInt(blkhsh,16);
        if(!isNaN(blknum)) {
            for(bi in Un.BLOCKS.blFrom) {
                if(Un.BLOCKS.blFrom[bi]==blkhsh) {
                    bl=bi; break;
                }
            }
        }
        else {
            var blkspc=blkhsh.split(Un.HASH_BLOCK_SPACE).join(" ");
            for(bi in Un.BLOCKS.blName) {
                if(Un.BLOCKS.blName[bi]==blkspc) {
                    bl=bi; break;
                }
            }
        }
    }
    else if(document.location.hash!="") {
        var hexhsh=document.location.hash.split("#").pop().split(Un.HASH_CP_PREFIX).pop().split("x").pop(); //if the cp_prefix is missing, or if prefixed with x, this will still work :)
        if(hexhsh.length==4 && !isNaN(parseInt(hexhsh,16))) {
            cp=hexhsh;
            for(bi in Un.BLOCKS.blFrom) {
                if(Un.BLOCKS.blFrom[bi]&gt;cp) {
                    bl=bi-1;
                    break;
                }
            }
        }
    }
    if(bl&gt;-1) {
        Un.selectBlock(bl,(cp==-1 ? 0 : 1));
    }
    else {
        Un.next(1);
        Un.setMenuButton($("#BlockButton"),0);
    }
    if(cp!=-1) {
        setTimeout("Un.cpOpen('"+cp+"')",100);
    }
}
