Question

我想从Google Maps API下载路线面板作为文本文件。我成功了，但该文本文件也有HTML标签。我只需要方向字符串。

如何使用java脚本删除该字符串？

任何帮助都将不胜感激。

感谢您提前。

我的代码在这里，

function saveTextAsFile(response) {
    var firstPath = response.routes[0].legs[0].steps;
    var textContent = "";

    for (var index in firstPath) {
        var ins = firstPath[index].instructions;
        textContent += ins + "\n";
    }

    location.href = 'data:application/downloads,' + encodeURIComponent(textContent)
}

我的输出如下：

Head <b>south</b> on <b>Pallavaram Kundrathur Main Rd/Pammal Main Rd</b> toward <b>Vedagiri St</b><div style="font-size:0.9em">Pass by SBI ATM (on the right)</div>
Turn <b>right</b> onto <b>Indira Gandhi Rd</b><div style="font-size:0.9em">Pass by Canara Bank (on the left in 350&nbsp;m)</div>
Turn <b>right</b> at <b>Pallavaram Signal</b> onto <b>NH45</b><div style="font-size:0.9em">Pass by DCB Bank Atm - Pallavaram Branch (on the left)</div>
Turn <b>left</b> onto <b>Dharga Rd</b>
Turn <b>left</b> toward <b>Siva Sankaran St</b>
Take the 1st <b>right</b> toward <b>Siva Sankaran St</b>
Take the 1st <b>left</b> onto <b>Siva Sankaran St</b>
Slight <b>right</b> at <b>Pedistrian Crossing</b>
Turn <b>right</b> toward <b>Subramaniar Koil 2nd St</b>
Turn <b>left</b> onto <b>Subramaniar Koil 2nd St</b>

但我需要没有那个html标签

This similar question提供了一些从字符串中删除HTML标记的好方法，我个人最喜欢的是：

使用RegEx：textContent.replace(/<[^>]*>?/gm, '');
使用jQuery：jQuery(textContent).text();

我已经修改了你的功能以满足你的需要

function saveTextAsFile(response) {
    var firstPath = response.routes[0].legs[0].steps;
    var textContent = "";

    for (var index in firstPath) {
        var ins = firstPath[index].instructions;
        textContent += ins.replace(/<(?:.|\n)*?>/gm, ''); + "\n";
    }

    location.href = 'data:application/downloads,' + encodeURIComponent(textContent)
}

要仅删除标记，以下内容应该有效

function saveTextAsFile(response) {
    var firstPath = response.routes[0].legs[0].steps;
    var textContent = "";

    for (var index in firstPath) {
        var ins = firstPath[index].instructions;
        textContent += ins.replace(/<\/?[b]>/gm, '');
    }

    location.href = 'data:application/downloads,' + encodeURIComponent(textContent)
}
