innerhtml

I'm generating content dynamically and in some instances, I need to set a   as the only content of a <span> element. However, the following adds   as text vs adding a empty space: var foo = document.createElement("span") foo = document.createTextNode(" "); which makes sense, so I'm wondering, how would I add   correctly without (!) using innerHTML Thanks for help! You can use a unicode literal for a non breaking space : var foo = document.createTextNode("\u00A0"); CodeFanatic If you don't want to use innerHTML , you can use a hexadecimal escape. The most common: \x20 – standard space or \s

I need to Hide all <a> elements with text or innerHTML that matches the number 'foo' or a custom value using javascript or jQuery. <li><a href="#" class="dir">foo</a></li> I have tried jQuery(document).ready(function() { if (jquery().text().html("foo"){ ('li >a').fadeOut() } }); $('a:contains(foo)').hide(); Done. Or: var customValue = "foo" $('a').filter(function(){ return this.innerHTML === customValue; }).fadeOut(); With the later option you custom it a lot more, like: var customValue = "foo" $('a').filter(function(){ return this.innerHTML === customValue && $(this).closest('div').length; })

1. 在JavaScript 中使用innerHTML的缺点是什么？ 如果在JavaScript 中使用innerHTML，缺点是：内容随处可见；不能像“追加到innerHTML”一样使用；即使你使用+ = like“innerHTML = innerHTML +'html'”旧的内容仍然会被html替换；整个innerHTML内容被重新解析并构建成元素，因此它的速度要慢得多；innerHTML不提供验证，因此我们可能会在文档中插入有效的和破坏性的HTML并将其中断。 2. 解释MySQL 外连接、内连接与自连接的区别 交叉连接 又叫笛卡尔积，它是指不使用任何条件，直接将一个表的所有记录和另一个表中的所有记录一一匹配。 内连接 则是只有条件的交叉连接，根据某个条件筛选出符合条件的记录，不符合条件的记录不会出现在结果集中，即内连接只连接匹配的行。 外连接 其结果集中不仅包含符合连接条件的行，而且还会包括左表、右表或两个表中 的所有数据行，这三种情况依次称之为左外连接，右外连接，和全外连接。 左外连接，也称左连接，左表为主表，左表中的所有记录都会出现在结果集中，对于那些在右表中并没有匹配的记录，仍然要显示，右边对应的那些字段值以NULL 来填充。右外连接，也称右连接，右表为主表，右表中的所有记录都会出现在结果集中。左连接和右连接可以互换，MySQL目前还不支持全外连接。 3. 求1+2
