Question

我正在使用#include <stdio.h> int main(void) { int a = 0; int b = 0; int correctInput=0; int total_sum = 0; do { printf("Type the first number : \n"); scanf("%d", &a); printf("Type the second number : \n"); scanf("%d", &b); if(a<b) correctInput=1; else printf("The second number should be bigger than the first one.\n"); } while (correctInput ==0) ; while (a <= b) { total_sum += a; a++; } printf("Result : %d \n" , total_sum); return 0; }来清除sanitize-html编辑器的粘贴文本。

让我们说结果可能是像这样的文本字符串

draftJS

现在我需要将<h1 class="title"> President said "<b>Give this man a money</b>" and i agree </h1替换为"或«取决于条件。我该怎么做我试图弄清楚我是否可以使用» draftJS方法来完成它，但它似乎太复杂了。所以我认为修改html字符串更容易。

Answer 1

我猜你可以用两个正则表达式来做到这一点：

＆＃13;

    var inputString = `<h1 class="title">
      President said "<b>Give this man a money</b>" and i agree
    </h1>`
      , startingQuoteRE = / "/g
      , endingQuoteRE = /" /g
      , outputString = ''
      ;
    outputString = inputString.replace(startingQuoteRE, " «");
    outputString = outputString.replace(endingQuoteRE, "» ");
    // Or by chaining .replace
    // outputString = inputString.replace(startingQuoteRE, " «").replace(endingQuoteRE, "» ");
    console.log(outputString);

＆＃13;

Answer 2

创建replaceAll功能。因为replace函数将替换唯一的第一次出现。

String.prototype.replaceAll = function(string, replace) {
return this.split(string).join(replace);
};

像这样调用函数。

var str = '<h1 class="title">\
President said "<b>Give this man a money</b>" and i agree\
</h1>';
var result = str.replaceAll('"','\'');
console.log(result);
