正则表达式在jquery或javascript中替换字符串，如下所述..

Question

jquery中的正则表达式替换字符串，如下所述。假设我有一个字符串，即

<#if ${x} == 'abc' > ${add} <#else if ${y} == 'dfg' > bef </#if>

在此，我要删除${和}部分内的所有if和else if。但不是在then部分，我怎样才能在jquery中进行呢？

Answer 1

var str="<#if ${x} == 'abc' > ${add} <#else if ${y} == 'dfg' > <#then ${y} == 'dfg' >";
var thenOut = str.split('then'); 
var required =thenOut[0].replace(/\$/g,"").replace(/\}/g,"").replace(/\{/g,"");
console.log(required+"then"+thenOut[1]);//heres what we need
