[英]Add blank spaces leaving HTML tags
I have a string that I want to check if it has words longer than or equal to 15 chars. 我有一个字符串,我想检查它的单词是否大于或等于15个字符。 If so, split that word to 5 chars by blank spaces, then return the same string with splitted words. 如果是这样,请将该单词拆分为5个字符,并用空格分隔,然后返回包含拆分单词的相同字符串。
My code works but the problem is that my string could also contain HTML tags and I would like to not touch them. 我的代码可以工作,但是问题是我的字符串也可以包含HTML标记,我希望不要碰它们。
function space_that(_e){
var w = [];
var t = $(_e).text();
w = t.split(" ");
for(var s in w)
if(w[s].length >= 15)
w[s] = w[s].substr(0,10) + " ";
$(_e).text(w.join(" "));
return true;
}
Just check if that part begins with an <, then it is an HTML tag. 只需检查该部分是否以<开头,那么它就是HTML标记。
function space_that(_e){
var w = [];
var t = $(_e).text();
w = t.split(" ");
for(var s in w) {
if(w[s].length >= 15
&& w[s].substring(0, 1) != "<"
&& w[s].substring(w[s].length-1, 1) != ">")
w[s] = w[s].substr(0,10) + " ";
}
$(_e).text(w.join(" "));
return true;
}
Edit: Corrected mistake (old answer affected ONLY html tags) and added check for opening and closing tags. 编辑:更正了错误(旧答案仅影响html标签),并添加了用于打开和关闭标签的检查。
Following version should work for tags with space inside. 以下版本适用于内部有空格的标签。
function space_that(_e){
var w = [];
var t = $(_e).text();
w = t.split(" ");
var inTag = false;
for(var s in w) {
if(w[s].substring(0, 1) == "<") inTag = true;
if(w[s].substring(w[s].length-1, 1) == ">") inTag = false;
if(inTag) continue;
if(w[s].length >= 15
&& w[s].substring(w[s].length-1, 1) != ">")
w[s] = w[s].substr(0,10) + " ";
}
$(_e).text(w.join(" "));
return true;
}
