javascript - 隐藏js元素

问题描述

我想隐藏一些给定条件的元素。我只是希望它们不要出现在 html 中。我试过了display: none。但是好像没有效果

我在想这样的事情：

    let beliefs_add_content = function(num_bins, tokens, divid, results = 0, show_submit = 1) {
    let inhtml = ""
    if (results == 1) {
        inhtml += "<div id=\"results_text\">\n";
        if (show_submit == 1) {
            inhtml += "<br>\n";
        }
        inhtml += "<br>\n";
        inhtml += "</div>\n";
    }
    if (results == 1; display: 'none' ) {
        inhtml += "<div id=\"top_div\">\n";
        inhtml += "<div id=\"question_div\"></div>\n";
        inhtml += "<div id=\"chart_wapper\">\n";
        inhtml += "<div id=\"bar_div\">\n";
        inhtml += "<div id=\"axis_div\"></div>\n";

        for (let i = 1 ; i <= num_bins ; i++) {
            inhtml += "<div class=\"bar_amt\" id=\"bar_amt" + i + "\">0</div>\n";
            inhtml += "<div class=\"div_bar\" id=\"bar" + i + "\"> </div>\n";
    }
        inhtml += "</div>\n";
        inhtml += "</div>\n";
        inhtml += "<div id=\"label_div\">\n";
        for (let i = 1 ; i <= num_bins ; i++) {
            inhtml += "<div class=\"label_val\" id=\"label" + i + "\" ></div>\n";
    }
        inhtml += "</div>\n";
        inhtml += "<div id=\"unallocated\">" + tokens + "</div>\n";
        inhtml += "<div id=\"prob_div\">\n";
        for (let i = 1 ; i <= num_bins ; i++) {
            inhtml += "<div class=\"prob_val\" id=\"prob" + i + "\" ></div>\n";
    }
        inhtml += "</div>\n";
        inhtml += "<div id=\"amount_div\">\n";
        for (let i = 1 ; i <= num_bins ; i++) {
            inhtml += "<div class=\"amt_val\" id=\"amt" + i + "\" ></div>\n";
    }
        inhtml += "</div>\n";
        inhtml += "<div class=\"slider_div\">\n";
        for (let i = 1 ; i <= num_bins ; i++) {
            inhtml += "\t<div class=\"cell_val\" id=\"cell" + i + "\">\n";
            inhtml += "\t\t<input type=\"range\" name=\"bin" + i + "\" id=\"bin" + i + "\" class=\"form-control slider\" value=\"0\" min=\"0\" max=\"" + tokens + "\" required/>\n";
            inhtml += "\t</div>\n";
    }
        inhtml += "</div>\n";
        inhtml += "<!-- Field for the alternative labels -->\n";
        inhtml += "<input type=\"hidden\" name=\"labelset\" id=\"labelset\" value=0 class=\"form-control\" required />\n";
        inhtml += "<div class=\"submit_div\">\n";
        inhtml += "<div id=\"submit_message\">&nbsp;</div>\n";
        inhtml += "<table id=\"submit_table\"><tr>\n";
        inhtml += "<td style=\"text-align:left;\">\n";
        if (beliefs_ns.beldat["bin_button"] != "") {
            inhtml += "<button class=\"btn btn-primary btn-large\" type=\"button\" id=\"alt_button\">Alternate Labels</button>\n";
    }
        inhtml += "</td>\n";
        inhtml += "<td style=\"text-align:right;\">\n";
        // We don't show the submit button on the final page
        if (show_submit == 1 & results == 0) {
            let onclick = (results == 0 ? "onclick=\"beliefs_ns.submit_click();\"" : "");
            inhtml += "<button class=\"btn btn-primary btn-large\" type=\"\" id=\"submit_button\" " + onclick + ">Submit</button>\n";
    }
        inhtml += "</td>\n";
        inhtml += "</tr></table>\n";
        inhtml += "</div>\n";
        inhtml += "</div>\n";
        $("#" + divid).html(inhtml);
}
}

但它工作得不是很好。有什么建议么？我需要发布额外的代码吗？
