Question

我有这个字符串，包含2个警告和3个错误，每个警告/错误由它的开始warning:或error:及其结尾_符号决定：

var data="warning:No data found_error:There's no data to display_error:Too many connections_warning:Test not passed:please check spelling_error:Connection lost";

如何让jQuery分别提取每个错误和警告？在这样的结构上：

if (data.indexOf("warning:") >= 0){
   var warnings.="<p class='warning'>"+EACHWARNINGHERE+"</p>";}

因此变量警告会存储此值：

var warnings="
<p class='warning'>No data found</p>
<p class='warning'>Test not passed:please check spelling</p>"

Answer 1

使用拆分：

var data="warning:No data found_error:There's no data to display_error:Too many connections_warning:Test not passed:please check spelling_error:Connection lost";
var a = data.split('warning:');//first split by `warning:`
var c = [];
var warnings = '';
for(var i in a){
    var b = a[i].split('error:');//now every part split again but by `error:`
    if(b[0]){
        warnings += "<p class='warning'>"+b[0].replace(/_$/,'')+"</p>";
    }
}

现在warnings是：

<p class='warning'>No data found</p>
<p class='warning'>Test not passed:please check spelling</p>

Answer 2

拆分'_'然后检查句子是否以'warning：'或'error：'

开头

var sentences = data.split('_')
for (var i=0; i<sentences.length; i++) {
    ver sentence = sentences[i];
    var sentenceType = data.slice(0,data.indexOf(':'));
    var sentenceText = sentence.slice(data.indexOf(':')+1);
    if (sentenceType == 'warning') {
       // add warning element with sentenceText
    }
    else {
       // add error element
    }
}
